Stata Weighted Least Squares Regression

votes

I realize this may be a novice question, but I'm still a beginner with Stata. I have a dataset that I'm trying to run a weighted least squares regression on, and I've installed the wls0 package. However, when I try to run my regression, I get a strange error:

option wvars() required r(198);

This doesn't happen when I try to run a regression for an example dataset used in a wls0 tutorial. Does anyone know anything about this?

do you have a variable in the wvars parameter of your regression? :) try following this example.. - Anthony Damico
That's an option, not a parameter. - Nick Cox

wls0 is from http://www.ats.ucla.edu/stat/stata/ado/analysis/ and requires such an option. So this is expected and in no sense surprising.
