## 2.5 Logic of argumentation

The Frequentist approach is based on deductive logic, this means that it starts from a statement about the true state of nature (null hypothesis), and predicts what should be seen if this statement were true. On the other hand, the Bayesian approach is based on inductive logic, this means that it defines what hypothesis is more consistent with what is seen. The former inferential approach establishes that the true of the premises implies the true of the conclusion, that is why we reject or not reject hypothesis. The latter establishes that the premises supply some evidence, but not full assurance, of the true of the conclusion, that is why we get probabilistic statements.

Here, there is a difference between effects of causes (forward causal inference) and causes of effects (reverse causal inference) (, ). To illustrate this point, imagine that a firm increases the price of a specific good, then economic theory would say that its demand decreases. The premise (null hypothesis) is a price increase, and the consequence is a demand reduction. Another view would be to observe a demand reduction, and try to identify which cause is more tenable. For instance, demand reduction can be caused by any positive supply shocks or any negative demand shocks. The Frequentist logic sees the first view, and the Bayesian reasoning gives the probability associated with possible causes.

# Which of the following is the formula of number average molecular mass $\bar{M_N}$?

$\begin{array}{1 1}(a)\;\bar{M_n}=\large\frac{\sum N_iM_i}{\sum N_i}&(b)\; \bar{M_n}=\large\frac{\sum N_iM_i}{\sum M_i}\\(c)\;\bar{M_n}=\sum N_iM_i&(d)\;\bar{M_n}=\large\frac{\sum N_iM_i^2}{\sum M_i}\end{array}$

If $N_1,N_2,N_3.......$ are the number of molecules with molecular masses $M_1,M_2,M_3,.......$ respectively,then the number average molecular mass is :
$\bar{M_n}=\large\frac{\sum N_iM_i}{\sum N_i}$
Hence (a) is the correct answer.

# Can oxidation of ethanol by copper(II) oxide yield copper(I) oxide as one of the products?

We know that ethanol is oxidised by copper(II) oxide to an aldehyde. Copper is reduced from $\ce{Cu^2+}$ to $\ce{Cu}$. Can this reaction, with some specific condition, yield $\ce{Cu2O}$ instead? That will also be a reduction of copper, only partial.

The question was asked on a Russian chem forum and it made me curious.

• If you add an excess of a reducing sugar to the mix, the copper(II) should all get reduced back to copper(I), i.e. Cu2O. I'm pretty sure that's not what you mean though ;) – airhuff Feb 18 '17 at 4:47

# question regarding grouping several variables

#### stats20

##### New Member
Hello!
In the context of regression, in what situations am I allowed to group separate variables into a single categorical predictor? I'll use R code as an example since it's what I'm most familiar with.
For example I could run a model like this:
Code:
dat <- data.frame(ind=c(1,2,3,4,5,6), y=c(40,63,23,66,74,45), day1=c(4,6,3,6,1,3), day2=c(6,4,7,9,8,9))
dat
ind  y day1 day2
1   1 40    4    6
2   2 63    6    4
3   3 23    3    7
4   4 66    6    9
5   5 74    1    8
6   6 45    3    9

mod <- lm(y ~ day1 + day2 + day1:day2, data=dat)
summary(mod)
Estimate Std. Error t value Pr(>|t|)
(Intercept) -133.873    230.464  -0.581    0.620
day1          33.121     41.781   0.793    0.511
day2          23.062     29.095   0.793    0.511
day1:day2     -4.046      5.289  -0.765    0.524
but I could also reshape dat in this way
Code:
dat2 <- melt(dat, id.vars = c("ind","y"))
dat2
ind  y variable value
1    1 40     day1     4
2    2 63     day1     6
3    3 23     day1     3
4    4 66     day1     6
5    5 74     day1     1
6    6 45     day1     3
7    1 40     day2     6
8    2 63     day2     4
9    3 23     day2     7
10   4 66     day2     9
11   5 74     day2     8
12   6 45     day2     9

mod2 <- lm(y ~ variable + value + variable:value, data=dat2)

summary(mod2)
Estimate Std. Error t value Pr(>|t|)
(Intercept)         47.7965    20.7469   2.304   0.0502 .
variableday2        -1.7345    41.7837  -0.042   0.9679
value                1.0531     4.9129   0.214   0.8356
variableday2:value  -0.2478     6.9479  -0.036   0.9724
The two approaches give very different results, and I'm not sure if one is considered more valid than the other.

Thanks!

Can you give a simple non-R example? or paste small runnable R code inside block ended by [/CODE] and started with [ CODE]
and include the data

#### hlsmith

##### Less is more. Stay pure. Stay poor.
Two questions:

1.) What is the purpose of the model. What model are you trying to run. Mod based on dat has only 3-way interactions.

2.) Look at what coefficients are generated from the model and that will help you distinguish what model is being ran. If they are generating different output than they are likely different models.

@obh I have updated my question with a runnable code.

#### obh

##### Well-Known Member
Hi Stat20,

The second model is incorrect ...even if you ignore the interaction X1X2

I will take one row for example:

In the first model:

X1 X2 X1X2 Y
4 6 24 40

In the second model:

X1 X2 X1X2 Y
4 0 0 40
0 6 0 40

Why do you expect to get the same answer ...

#### stats20

##### New Member
I do not expect the models to give the same answer, I was just wondering if the second model is valid. Why am I not allowed to have this structure?:
X1 X2 X1X2 Y
4 0 0 40
0 6 0 40

If y represents performance on math test and day1 and day2 are hours spent studying, maybe I would like to test if math scores can be predicted by a combination of time spent studying on day1 and day2. I realize that this is a repeated measures so to be accurate I should use a mixed model approach instead, but my question applies to the mixed model case as well.

#### obh

##### Well-Known Member
Hi S,

The following row is incorrect:
X1 X2 X1X2 Y
4 0 0 40

This is incorrect because when X1=4 and Y=40, X2 isn't equal 0 but it is equal 6.

You may decide for example to use only X1, or only X2
Y=a0+a1X1 okay.
Y=a0+a1X2 okay.
Y=a0+a1X1+a2X2 okay.

But you can't combine data of Y=a0+a1X1 and Y=a0+a1X2 in the same model.

I realize that this is a repeated measures.
This is not a repeated measure since you have only one DV (Y)
You have two predictors for one DV (the predictors may be dependent)

#### stats20

##### New Member
Thanks obh, that was very helpul. Do you mind if I ask you another question?
If I go with
Y=a0+a1X1
Y=a0+a1X2

do I need to correct for multiple testing?

This is not a repeated measure since you have only one DV (Y)
You have two predictors for one DV (the predictors may be dependent)
Oh I see. I thought repeated measures meant that I have more than two IVs per individual. In my case each individual is measured on two occasions: day1 and day2.
I'm sure I'm wrong, I'm just trying to understand

#### obh

##### Well-Known Member
Hi S,

You should choose the one model, the best regression model: Y=a0+a1X1 or Y=a0+a1X2 or Y=a0+a1X1+a2X2 or Y=a0+a1X1+a2X2+a3X1X2.
So no need to correct (unless you need to choose predictor which is a different story)

Repeat measure says that you measure for example the same subject more than once.
For example blood pressure before taking the medicine and after. (paired t-test)

When you have more than one predictor, this is multiple regression.
Again there may be a dependency between Day1 and day2

#### stats20

##### New Member
Hi obh,

A follow-up question, what if I use a mixed model (eg, lme4::lmer) for mod2 to account for the fact the data come from the same ind? Would it still be incorrect?

# pysal.explore.giddy.ergodic.fmpt¶

pysal.explore.giddy.ergodic.fmpt(P)[source]

Calculates the matrix of first mean passage times for an ergodic transition probability matrix.

Parameters: P : array (k, k), an ergodic Markov transition probability matrix. M : array (k, k), elements are the expected value for the number of intervals required for a chain starting in state i to first enter state j. If i=j then this is the recurrence time.

Notes

Uses formulation (and examples on p. 218) in [KS67].

Examples

>>> import numpy as np
>>> from pysal.explore.giddy.ergodic import fmpt
>>> p=np.array([[.5, .25, .25],[.5,0,.5],[.25,.25,.5]])
>>> fm=fmpt(p)
>>> fm
array([[2.5       , 4.        , 3.33333333],
[2.66666667, 5.        , 2.66666667],
[3.33333333, 4.        , 2.5       ]])

Thus, if it is raining today in Oz we can expect a nice day to come along in another 4 days, on average, and snow to hit in 3.33 days. We can expect another rainy day in 2.5 days. If it is nice today in Oz, we would experience a change in the weather (either rain or snow) in 2.67 days from today. (That wicked witch can only die once so I reckon that is the ultimate absorbing state).

Maximum SCC size in a directed graph if one new edge can be added.

Revision en2, by r3novatio, 2020-10-27 10:07:27

I came across this problem in which you have been given a directed graph $G=(V,E)$ with $|V|,|E|\leq 10^5$ and one additional edge can be added to $E$. What can be the maximum size of a strongly connected component in the resulting graph?

If anyone knows an approach, do share.

Thanks.

EDIT: I apologize that the $O(V.(V+E))$ algorithm that I thought would solve this also turned out to be incorrect.

### JEE Main 2021 (Online) 31st August Evening Shift

A bob of mass 'm' suspended by a thread of length l undergoes simple harmonic oscillations with time period T. If the bob is immersed in a liquid that has density $${1 \over 4}$$ times that of the bob and the length of the thread is increased by 1/3rd of the original length, then the time period of the simple harmonic oscillations will be :-
A
T
B
$${3 \over 2}$$T
C
$${3 \over 4}$$T
D
$${4 \over 3}$$T

## Explanation

$$T = 2\pi \sqrt {l/g}$$

When bob is immersed in liquid

mgeff = mg $$-$$ Buoyant force

mgeff = mg $$-$$ v$$\sigma$$g ($$\sigma$$ = density of liquid)

$$= mg - v{\rho \over 4}g$$

$$= mg - {{mg} \over 4} = {{3mg} \over 4}$$

$$\therefore$$ $${g_{eff}} = {{3g} \over 4}$$

$${T_1} = 2\pi \sqrt {{{{l_1}} \over {{g_{eff}}}}}$$

$${l_1} = l + {l \over 3} = {{4l} \over 3},\,{l_{eff}} = {{3g} \over 4}$$

By solving

$${T_1} = {4 \over 3}2\pi \sqrt {l/g}$$

$${T_1} = {{4T} \over 3}$$

Four identical hollow cylindrical columns of mild steel support a big structure of mass 50 $$\times$$ 103 kg. The inner and outer radii of each column are 50 cm and 100 cm respectively. Assuming uniform local distribution, calculate the compression strain of each column. [Use Y = 2.0 $$\times$$ 1011 Pa, g = 9.8 m/s2]
A
3.60 $$\times$$ 10$$-$$8
B
2.60 $$\times$$ 10$$-$$7
C
1.87 $$\times$$ 10$$-$$3
D
7.07 $$\times$$ 10$$-$$4

## Explanation

Force on each column = $${{mg} \over 4}$$

Strain = $${{mg} \over {4AY}}$$

$$= {{50 \times {{10}^3} \times 9.8} \over {4 \times \pi (1 - 0.25) \times 2 \times {{10}^{11}}}}$$

= 2.6 $$\times$$ 10$$-$$7

A uniform heavy rod of weight 10 kg ms$$-$$2, cross-sectional area 100 cm2 and length 20 cm is hanging from a fixed support. Young modulus of the material of the rod is 2 $$\times$$ 1011 Nm$$-$$2. Neglecting the lateral contraction, find the elongation of rod due to its own weight.
A
2 $$\times$$ 10$$-$$9 m
B
5 $$\times$$ 10$$-$$8 m
C
4 $$\times$$ 10$$-$$8 m
D
5 $$\times$$ 10$$-$$10 m

## Explanation

We know,

$$\Delta l = {{WL} \over {2AY}}$$

$$\Delta l = {{10 \times 1} \over {2 \times 5}} \times 100 \times {10^{ - 4}} \times 2 \times {10^{11}}$$

$$\Delta l = {1 \over 2} \times {10^{ - 9}} = 5 \times {10^{ - 10}}$$ m

# How to: Navigate Through the Objects in a Data CollectionView

Views allow the same data collection to be viewed in different ways, depending on sorting, filtering, or grouping. Views also provide a current record pointer concept and enable moving the pointer. This example shows how to get the current object as well as navigate through the objects in a data collection using the functionality provided in the CollectionView class.

## Example

In this example, myCollectionView is a CollectionView object that is a view over a bound collection.

In the following example, OnButton is an event handler for the Previous and Next buttons in an application, which are buttons that allow the user to navigate the data collection. Note that the IsCurrentBeforeFirst and IsCurrentAfterLast properties report whether the current record pointer has come to the beginning and the end of the list respectively so that MoveCurrentToFirst and MoveCurrentToLast can be called as appropriately.

The CurrentItem property of the view is cast as an Order to return the current order item in the collection.

//OnButton is called whenever the Next or Previous buttons
//are clicked to change the currency
private void OnButton(Object sender, RoutedEventArgs args)
{
Button b = sender as Button;

switch (b.Name)
{
case "Previous":
myCollectionView.MoveCurrentToPrevious();

if (myCollectionView.IsCurrentBeforeFirst)
{
myCollectionView.MoveCurrentToLast();
}
break;

case "Next":
myCollectionView.MoveCurrentToNext();
if (myCollectionView.IsCurrentAfterLast)
{
myCollectionView.MoveCurrentToFirst();
}
break;

o = myCollectionView.CurrentItem as Order;
// TODO: do something with the current Order o
}
}

'OnButton is called whenever the Next or Previous buttons
'are clicked to change the currency
Private Sub OnButton(ByVal sender As Object, ByVal args As RoutedEventArgs)
Dim b As Button = TryCast(sender, Button)

Select Case b.Name
Case "Previous"
myCollectionView.MoveCurrentToPrevious()

If myCollectionView.IsCurrentBeforeFirst Then
myCollectionView.MoveCurrentToLast()
End If

Case "Next"
myCollectionView.MoveCurrentToNext()
If myCollectionView.IsCurrentAfterLast Then
myCollectionView.MoveCurrentToFirst()
End If
Exit Select

o = TryCast(myCollectionView.CurrentItem, Order)
' TODO: do something with the current Order o
End Select
End Sub

# Understanding this peak detector circuit

Assuming ideal diodes, for $$\V_{in} \lt 0\$$ this is an inverting op amp with gain $$\\frac{R_3}{R_1}\$$, and $$\R_2\$$ keeps the non inverting input from floating. For $$\V_{in} \gt 0\$$, this is a buffer. The circuit probably makes the most "sense" if $$\R_3=R_1\$$, but if $$\R_3 \ll R_1\$$, than you are getting something akin to half wave rectification instead of full wave.

You are correct about the low pass filter, but since you are low-pass filtering a rectified signal, this is more like an rms-filter or envelope detector.

I wouldn't call it a "peak detector", as those usually store the peak value on a cap with no discharge path. Here, the cap discharges through a resistor, so the voltage is not stored.

The opamp circuit is a full wave rectifier with some level of noise rejection when the input peak amplitude starts to fall below about 0.6 volts. Positive voltages are amplified by D2 (D1 is blocking) and negative voltages are amplified and inverted via D1 (D2 is now blocking). R2 is needed to bias the non-inverting opamp input when the device is inverting i.e. D2 is blocked. R1 and R3 should be identical values.

The low pass filtering effect of C1 affects both positive and negative input voltages differently and is probably incidental to the whole circuit operating as a full wave rectifier.

Because it is a full wave rectifier, the envelope detector is fed with twice as many carrier cycles per second and hence it can deliver a better performance compared to when feeding the raw input signal directly to it.
