Re: weighted histogram or distribution graph

"Survey weights" is ambiguous, but I'm assuming you mean frequency weights or the equivalent... I hate to be the bearer of bad news but while there are many tasks you might want to do where you can easily do things to approximate frequency weights, the distributions calculations are going ...

Re: Transition Matrix Parameters

The convention that we use is as described in the documentation as P(i, j) = Pr(S_t = j | S_t-1 = i). . P21 is Pr(S_t = 1 | S_t-1 = 2), or from 2 -> 1. . So if I am thinking clearly this morning, in your case, increases in UNEMPAPR16 lowers the probability of transferring from 2->1, and increases th...

Re: Correlation errors in state space models

Fair enough on the suggestion for the docs. The idea seemed straightforward when written, but I can see why it might not be obvious. For now, let's try this a different way. Rather than me try to figure out your particular model, here is the basic idea for getting the correlation timing .(Note that ...

Re: Correlation errors in state space models

Can you be more specific about the process you want to impose for your states? How do they evolve?

Re: Obtaining weights with Principal component analysis

I must admit that I don't entirely understand what you are trying to do with your calculation. The following shows the equivalence between post-multiplying the data by the eigenvectors and the score series created using normalize loadings scaling. Note that as expected the average sum of the squared...

Re: Fixed Effects- Industry and Year

In the language of factors, multiple terms in @expand gives the interaction effects, but not the main effects.

Re: Confidence Intervals: Forecast vs. Makemodel

Is there a chance you can share your workfile. In all of my test cases I'm not seeing this discrepancy. (Note that the model simulation doesn't include the coefficient uncertainty, but in my cases, I'm not seeing much difference from that).

Re: Fiscal/Academic year labeling

Question, you can always create an undated workfile with that kind of labeling. Is there anything that you need date wise that isn't handled by an undated with custom labels?

Re: Expected to see Eviews Workfiles Encryption

It is an interesting idea and I can understand the appeal There are, however, legal issues that make this not quite as simple a request as one might think. Given this fact and the existence of third-party encryption tools which can be used to encrypt a workfile, this feature is currently not high on...

Re: Copy values from cross-section to entire vector

Can you be a bit more specific about what you are doing? What values in AA need to be copied? Is it the value for one date, or values for a range of dates? Are we matching up observations by-date?
