Re: F-test / Wald Test discrepancy

I think your R^2 formula is wrong. Maybe the k-1 should be the number of restrictions, r

Re: F-test / Wald Test discrepancy

You'd have to post both sets of information for anyone to compare them.

As a wild guess, the sample changed when you did it manually.

Window refresh bug

Here's a screenshot showing a refresh bug. Look at the row title on the cross-tab. What happened is that I dragged another window across this one and then dragged it off. Yes, I've done it twice with the same result.

Re: Tables that contain series that sometimes aren't populated

One option--might or might not meet your needs--is to create the series and set them equal to NA. Then your code can populate them with real values or just leave them alone.

Re: "Log of non-positive number"

Logs can be negative, but the logs of a non-positive number don't exist.

@inlist delimitor

Maybe a version of @inlist which uses a comma for a delimitor? Not only would this be useful for people who don't RTFM and see you're supposed to use a space for a delimitor, it would also help for alpha series like "New York"

Shrinking workfile

This may be the dumbest question I've asked here in a while...

How do I save an EViews workfile while dropping observations not in the smpl? I have a 500MB workfile I need to shrink.

Re: Speeding up simulations

Be sure that under general options/advanced you have Compile to machine code on and multiprocessor use set to auto. But you probably do because these are the defaults. More RAM probably doesn't matter so long as you have enough to contain everything in memory. Unless you are doing a problem with an ...

Re: Merging coefficient in series (Updated) - Not correct mean

The answer is that you can't use @vars or @std. Those divide by n-1. The regression has a constant and X. The SSR needs to be divided by n-2. Do that and I think everything will work.

Re: Merging coefficient in series (Updated) - Not correct mean

I will admit to being puzzled.

A small piece of where I'm puzzled is what we're seeing for exp_var. Isn't that a series 10,000 long?

Re: Merging coefficient in series (Updated) - Not correct mean

Something about this is bothering me. Shouldn't the expected variance of the residuals asymptotically approach (from below) the true variance of the generating process (as written in the original author's script) as the sample size increases? The extreme boundary example is n = 2, where the residua...

Re: Merging coefficient in series (Updated) - Not correct mean

Actually, one more possibility: You're looking at something wrong. Is your copy of EViews up-to-date?

I ran the code you posted and got a mean of 3.9938.
