Hello,



I trying to find a way to calculate a bivariate bandwidth for a bivariate local polynomial regression and I have a question.



Somebody know if I can use the instruction "dpill" to do it?

When I read the instructions I see that "x" must be a vector of variables, but if I state "x" is a matrix with 2 columns the program also works.



Please, somebody can help me?

Thanks a lot

Alexandra
