RE: st: RE: Correlation among residuals

I guess that you have several variables whose names begin with "year", but not "year" itself. 

So -tsset- aborted with error. Nothing dependent on -tsset- will work. 

. d year* 

should help to diagnose this problem. You need to give the _full_ variable name.

I mean when I run regression with tobit method and then I used "tsset
year, yearly" command, stata mentioned that "year ambiguous
abbreviation", so I do not know how to solve this problem.
