### Re: logit standard error

I think you've done everything correctly. But you may be misinterpreting significance.

Suppose c(1) is almost exactly zero, so not "significant." Then

1/(1+exp(c(1))) = 1/(1+e^0)=1/(1+1) = 0.5

which is significantly different from zero.

### Re: Marginal effects multinomial logit model

E-11 is scientific notation for times 10 to the minus eleventh power. It is not an error.

### Re: logit standard error

It’s a touch messy. Basically var(f(b)) = f’(b)var(b)f’(b), where f’ means first derivative.

Probably the easiest way to get the standard error is to look under coefficient,views,wald test and test

Code: Select all

`1/(1+exp(c(1)))=0`

### Re: Program to run with existing workfile

I am not shying from doing work, I am having a difficult time trying to find the instructions that tell the program to select an equation from an open workfile, change a given variable and then evaluate the equation for a given number of times and then store the SSR, similar to your example storing...

### Re: Program to run with existing workfile

Presumably, something changed in the equation between runs. You'll have to reference the equation object after each run.

### Re: Program to run with existing workfile

Once you run an equation, it remembers all the values it produces until you change something. No need to re-run it. Also, you can run it once and save the value you want in a scalar for easy later reference.

### Re: Multiplying Na by zero

One way

Code: Select all

`series newVar = @recode(oldvar1=na,0,oldvar1)*@recode(oldvar2=na,0,oldvar2)`

or something like that, although that would also give NA*7 = 0 which may not be what you want.

### Re: Panel VAR EViews 9

Is it possible do do some of this by manually writing out the VAR as a standard regression?

### Re: Insufficient observations

EViews starts estimation with whatever is stored in the c vector. In your case, this is causing some division by zero. Try saying

Code: Select all

`c = 1`
before you start the estimation.

### Re: Near Singular Matrix Error

Perhaps you should ask your instructor why normality matters in this application.

After all, lots of things just aren't normal.

### Re: Near Singular Matrix Error

(1) You haven't said what the problem is. Non-normality does not invalidate a VAR.
(2) Sometimes you can take logs or make other transformations of the data to make residuals more normal.
