cross validation optimal bandwidth

[Allan Andreotti]

hi, i found that you can obtain the optimal bandwidth using CV with with lpoly command. However it requires multiple inputs. And i only need the optimal bandwidth for only one variable using CV.
Thank you

Hi Allan
I dont think that is correct. Lpoly uses a Rule of thumb for setting the bandwidth for the regression.
I would suggest you to use -npregress kernel- to obtain the CV optimal bandwidth
