Description

Hello,

First of all, thanks for the great package. I'm trying to compute density maps of a 3 dimensional points distribution. I understood from the documentation that a variable bandwith method was available but I couldn't figure out how to set up this option. Additionnaly, in the case of a fixed bandwidth KDE for multidimensional data, I would have expected as in the stats_models_multivariateKDE implementation to be able to use a bandwidth per dimension but it seems that we can either use a single value of the bandwidth or to use one bandwidth per data point. Is it in order to take into account the weight of each data point that you implemented it this way ?

Thanks in advance.

Cheers Yoann
