Kernel density estimation with polyspherical data and its applications

Eduardo García-Portugués, Andrea Meilán-Vila

A kernel density estimator for data on the polysphere ${\mathbb{S}}^{d_1}\times \cdots \times {\mathbb{S}}^{d_r}$, with $r,d_1,\dots ,d_r\ge 1$, is presented in this paper. We derive the…
