Clustering and Simulation of Spherical Cauchy and PKBD Models

Provides tools for estimation and clustering of spherical data, seamlessly integrated with the 'flexmix' package. Includes the necessary M-step implementations for both Poisson Kernel-Based Distribution (PKBD) and spherical Cauchy distribution. Additionally, the package provides random number generators for PKBD and spherical Cauchy distribution. Methods are based on Golzy M., Markatou M. (2020) , Kato S., McCullagh P. (2020) and Sablica L., Hornik K., Leydold J. (2023) .
