st: estimating partially linear model

[Berk Sensoy <berksensoy@gmail.com>]

Hi all,

Is there a command in stata to estimate (nonparametrically) models of the form:

y = f(x) + delta'z 

where z is a vector of controls and f(.) is the function to be
estimated?  I know fracpoly will do something similar, but is there a
way to do it nonparametrically?

Thanks!
