%description
Provides implementation of statistical methods for random objects lying in
various metric spaces, which are not necessarily linear spaces. The core
of this package is Fréchet regression for random objects with Euclidean
predictors, which allows one to perform regression analysis for
non-Euclidean responses under some mild conditions. Examples include
distributions in 2-Wasserstein space, covariance matrices endowed with
power metric (with Frobenius metric as a special case), Cholesky and
log-Cholesky metrics, spherical data. References: Petersen, A., & Müller,
H.-G. (2019) <doi:10.1214/17-AOS1624>.
