Re: Coefficient uncertainty in stochastic model solve -- log

I see. I am now trying to solve the model in the new way and running into errors of the kind "Calculating Innovation Covariance Matrix Sample: 1900 1979 Insufficient PPRIM innovations - Equation treated as non-stochastic Insufficient PSEC innovations - Equation treated as non-stochastic Matrix ...

Re: Coefficient uncertainty in stochastic model solve -- log

Thanks, Chris. My model is created by first creating equation estimation objects that are then appended to a model object. Here's a code snippet (never mind the specific variable names, of course): EQUATION _PS.tsls log(QSprim) c log(Pprim) log(Pwages) log(Penergy) log(CAP) log(QSprim(-1)) @ log(Pwa...

Re: Coefficient uncertainty in stochastic model solve -- log

Well, it seems that it's not quite so simple. I went back to the model and ran a stochastic solution with coefficient uncertainty turned on and turned off, and the results are nearly identical (some difference between them, of course, but very similar). This suggests that the coefficient uncertainty...

Re: Coefficient uncertainty in stochastic model solve -- log

Got it. Thanks for the quick reply.
I suspected that the documentation might be in error given that the command was giving me what seemed to be random draws from the coefficients.

Coefficient uncertainty in stochastic model solve -- loglog

I have a question about how EViews handles a stochastic model solution for a model in log-log form. For instance, I have a supply and demand model that looks something like this: log(Y1) = B1*log(X1) + B2*log(X2) + B3*log(X2(t-1)) + B4*log(Y1(t-1)) + u log(Y2) = A1*log(X1) + B2*log(W2) + B3*log(W2(t...

How to make model.append parse @ data members?

What I'm trying to do is make a model that consists of the lower 95% confidence interval for a set of equations. Rather than type everything in by hand, I'm trying to make use of the @coefs and @stderrs data members of the equation object. Here's what I would expect to work: EQUATION eq.ls VAR1 c VA...

Thanks! I figured it was obvious... There's just too many manuals... never know where to look :p

Function for calculating mean-difference hypothesis test?

Sorry if this is obvious or appears in the forum or manual somewhere... I tried for far too long to try and find it (I could have just programmed the formula instead in the time I spent...) Is there a way to get the functionality of SERIESX View->Descriptive Statistics & Tests->Simple Hypothesis...

replace NAs by 0 in for loop over multiple series

I couldn't quite piece together how to accomplish this seemingly simple task. I have multiple series that I want to replace NAs by 0. I know for a single series I use X=@recode(X=na,0,X) But I can't figure out how to loop over a list of series I specify Something like for %i SERIES1 SERIES2 SERIES3 ...

Calculate forecast statistics from model solution?

When you forecast an equation in Eviews, you can see forecast statistics such as RMSE and Thiel's U. Since model solutions are just forecast reduced form equations, is it possible to get these statistics for each endogenous forecast in a model forecast?

Baseline scenario is overwritten when using an add factor?

I'm running into an issue when I use an add factor to change the solved values of an endogenous variable in a scenario. The add factor successfully changes the solved values of the variable in the scenario, but it *also* changes the values in the baseline scenario. Using the following code: smpl @al...
