I can`t find the help file for xtlsdvc command
I`ve downloaded one but it doesn`t work
> The finite-sample bias approximations used by xtlsdvc
> requires an estimate of the regression variance. So
> the estimator is implemented into two steps:
> 1) get the variance estimate from residuals obtained
> from some *initial* estimator
> 2) work out bias approximations and correct LSDV
