Subject | st: weights with Gaussian Kernel in lpoly, Stata 11 |
Date | Wed, 29 Aug 2012 11:18:32 +0200 |
Dear Statalist users,In a nonparametric regression using the lpoly command, I would like to put different weights on observations.
However, when I want to use the Gaussian Kernel, I get the following error: cross(): 3200 conformability error _lpoly_work(): - function returned error <istmt>: - function returned error For all the other kernels, the option [aw] runs.Could you tell me if there is something special with the Gaussian kernel or if it is a bug in the lpoly ?
I'm using Stata 11. Here is the code I used: set obs 300 drawnorm x3 e gen x32=x3^2 gen y=x3+2*x32+e gen d=uniform() lpoly y x3 [aw=d], kernel(gaussian) lpoly y x3 [aw=d], kernel(epan2) Already many thanks for your answer.
