do you know if in Stata is implement Ichimura's Semi-parametric Least
Squares (SLS) from Ichimura (1993): "Semiparametric Least Squares
(SLS) and Weighted SLS Estimation of Single-Index Models," Journal of
Econometrics?
I want to estimate the quantile regression correct for selection, the
same approach of Buchinsky( Buchynsky: The dynamic of changes in the
female wage distribution in the usa: a quantile regression approch JAE
1998).
Could you give me some information?
Thank you very much in advance.
