### Re: Dummy Variables

Thanks, it works for the system specification. Now there is another problem, when I try to estimate. I have a system of 25 equations, with 3 independent variables for each. I then try to perform the estimation with the Seemingly Unrelated Regression method and it works well. But when I add fixed eff...

### Re: Dummy Variables

A related question: I constructed a system of equations to estimate with Seemingly Unrelated Regressions (SUR). The system has to specified with each actual coefficient related to the associated variable, for example: Under System Specification: Ycounty0 = C(1)*rain0+C(2)*clouds0+C(3)*x0+C(4)*sun0 Y...

### Re: Dummy Variables

Thanks, tried it and seems to construct the dummies well but when performing a standard OLS in levels using @expand(hourmonthyear,@dropfirst) I get an error message: Matrix size error : too many parameters for default coefficient vector. I have nearly 30000 observations (using 2.5 years of the data)...

### Re: Dummy Variables

Basic version: Basically I would like to have something like to create 1440 time dummies, one for each hour over 5 years. Using expand does not work since it only allows two timeframes, so I would like to use expand(@hour,@month,@year) but it doesn't work. What would be the alternative? I've looked ...
