Combining local and global smoothing in multivariate density estimation
Adelchi Azzalini · Stat · 2016
Non‐parametric estimation of a multivariate density is tackled via a method that combines traditional local smoothing with a form of global smoothing but without imposing a rigid structure. Simulation work delivers encouraging indications on the effectiveness of the method. An application to density‐based clustering illustrates a possible usage. Copyright © 2016 John Wiley & Sons, Ltd.
