Re: two way panel

The @expand dummies would need to be treated by the @meansby demeaning, no?

Re: two way panel

If you have three variables, say Y, X1, and X2, you can easily demean using frml ydm = y - @meansby(y, id) frml x1dm = x - @meansby(x1, id) frml x2dm = x - @meansby(x2, id) where ID is the categorization variable corresponding to the 10,000 dummies. The result will be the series with means-by-categ...

Re: two way panel

One dimension has about 100 categories. That'll work. The other has 20,000. I need something to sweep out the dummies.

I would understand that if it weren't @expand. What can be multicollinear with a set of dummy variables?

Re: near singular

I can't, as it's confidential. Is there something you want me to do to shed light on the issue?

That's kind of what I thought. The issue is that sometimes one wants to do fixed effects and there's no way to do that without creating a panel.

near singular

The command

Code: Select all

ls grade_num @expand(course_dept_code)

works for an unstructured file. When I turn the file into a panel with a different variable for the id, I get nonsingular matrix.

Uh, what's going on?

two way panel

(This may not be the most clever question ever.) I would like to create a two-way panel so I can use two sets of fixed effects. Think of one id being a student grade and the other being a department. The two together do not give a unique identifier, since a student may take multiple courses in one d...

The student versions do not support add-ins according to the EViews web site.
