### Re: How do I set an initial coefficient value in a State Space object from a previously calculated scalar?

This program seems to run just fine for me: wfcreate(wf=annual, page=myproject) a 1950 2005 genr series1=nrnd genr series2= 0.9*series1(-1)+ 0.1*nrnd ' Working state space statespace locallevel ' Create and estimate the state space with initial values locallevel.append @signal series2=mu +[ename = e...

### Re: How to use temporary variables in state space?

I'm not sure I follow what you're doing. The first element in longnames will be equal to: "series1gdp" Then, inside your for loop, you store that value into %stringtemp2, then create a series with a name of whatever is inside %stringtemp2, followed by "gdp". Thus, the first time ...

My bad, try it without the braces.

### Re: Adding @stochastic to a model text file

ah, not really. Just the long way of removing the equation, then re-adding it with the @identity at the start.

### Re: Handle two temporary control variables in nested loops

Not sure I follow. If I run your code I get this:
2022-05-13_090044.png (113.51 KiB) Viewed 107 times

Which seems to be what you think should happen?

As an aside, you should probably be using svectors rather than alphas.

### Re: Equation System

Just write out the equations in coefficient form:

Code: Select all

`Y=c(1)+c(2)*xZ=c(3)+c(4)*w`

### Re: Dependent variable has no variance - Logit regression

Perhaps. I’m just trying to figure out if it is a calculation issue or a data issue

### Re: Dependent variable has no variance - Logit regression

Just choose the first 1500 observations plus any observations where y=1.

Code: Select all

`smpl @all if @trend<1500 or y=1`

### Re: Dependent variable has no variance - Logit regression

What happens if you reduce the sample dramatically, keeping the 115 1s, but only including, say, 1500 0s?
