Uniformity Tests on the Circle, Sphere, and Hypersphere

Implementation of uniformity tests on the circle and (hyper)sphere. The main function of the package is unif_test(), which conveniently collects more than 30 tests for assessing uniformity on S^{p-1}={x in R^p : ||x||=1}, p >= 2. The test statistics are implemented in the unif_stat() function, which allows computing several statistics to several samples within a single call, thus facilitating Monte Carlo experiments. Furthermore, the unif_stat_MC() function allows parallelizing them in a simple way. The asymptotic null distributions of the statistics are available through the function unif_stat_distr(). The core of 'sphunif' is coded in C++ by relying on the 'Rcpp' package. The package also provides several novel datasets and gives the reproducibility for the data application in García-Portugués, Navarro-Esteban and Cuesta-Albertos (2020) .
