RooFit kernel density estimation

Dear root users,
I need help on using RooKeysPdf to fit data.
1.I m not certain how to find the best smoothing parameter which fits the data.
Is there any technique to find the best smoothing parameter ?

           2. What is the technique used in RooFit (RooKeysPdf) to find the optimum band with for the kernels.

Thanks.
