I included the following in the model: mod1.append r = @rsum(all) The model compiles with no errors, but when the model can't solve ("unable to compute due to missing data"). So I decided to do it the long way: I appended each of the 40 leads (from zz = rtb(!x)*(0.98^!x)*(1 - 0.98)/(1 - 0....

Ok, I understand what you mean now.

Thanks,

So you can't see a way to solve my problem, either by eliminating the need for a loop or including a loop in the model?

Matt

The results are identical for the two loops.

Thanks again for your help.

Hi, I'm wondering if it is possible to include a loop inside a model. My model consists of single equations for GDP, inflation, the Fed funds rate, and the long-term interest rate. Here is the tricky part: the long-term interest rate in each quarter is a weighted sum of the short-term rate over the ...

Here is my loop:

genr z = 0
for !x = 0 to 39
genr zz = r(!x)*(b^!x)*(1 - b)/(1 - b^40)
genr z = z + zz
next


What do you think? Could it be done any better?

Hi, I'm trying to figure out how to code summation notation into Eviews 7. See attachment for what exactly I'm trying to do. Basically, this notation creates a time series, where the value for each time period t equals a weighted sum over the next 40 periods. R is a time series. I've written a loop,...

For the Endogeneity test, the null is that the instrument subset is exogenous. I don't understand why the null refers to the instrument subset rather than the regressor subset. Are you referring to the Instrument Orthogonality Test, perhaps? For the Regressor Endogeneity Test, I thought the purpose...

I am using Eviews 7. I am doing GMM estimation and want to use the IV diagnostics and tests that Eviews has available. But I am having difficulty interpreting the test results. For the regressor endogeneity test, is the null hypothesis that the regressors are endogenous (for example, the p-value I'm...
