Hello to everybody,
Somebody know how I can apply the instruction (regband) of the package (locfit)
to a multivariate covariate. In the instructions states that the formula has to
have only one predictor.
How can I use that when I have an unknown function with two predictors, m(X,Z)?
Is there any other way to get a bivariate bandwidth in a local regression
polynomial?
I'll appreciate any query. I'm very lost and very desperate. I cannot
find a solution.
Thank you a lot in advance.
Alexandra
