Hello all, I need to compare effects on a dependent variable based on different levels of an independent one, x2 in the attached equation. I want to look at the effect on predicted y when x2 changes from 4 to 7 http://i.imgur.com/pFDHmXG.jpg I'm using eviews 7 and what I did was I sampled x2 based o...

Thanks guys! One more question. I'm trying to run a White Test on a series with 10,000 obs. The chi squared is much, much higher than obs*r-squared and my professors don't seem to have used that method. They just mention that the result of an example has "low power" indicating heteroskedas...

Oh wait!

Question, if I'm regressing income against age, education, and experience, for example, I'd use

ls inc age edu exp c.

But then if I set age=25, then I'd use the sample and go with IF age=25 and run the regression without the age variable as

ls inc edu exp c, right?

The thing is, regressing it against age produces a regression with no issues. It's only when I set age to something, say age=25, that it says it's a singular matrix...

Hello, I hope this is in the correct forum. I'm using eviews 7 to do a regression on cross sectional data but I need to know how to compare outputs between different values for a variable. For example, if I'm regressing income against age, I want to examine the effects of age=25 and age=30. How exac...
