%description
Robust estimation methods for the mean vector, scatter matrix, and
covariance matrix (if it exists) from data (possibly containing NAs) under
multivariate heavy-tailed distributions such as angular Gaussian (via
Tyler's method), Cauchy, and Student's t distributions. Additionally, a
factor model structure can be specified for the covariance matrix. The
latest revision also includes the multivariate skewed t distribution. The
package is based on the papers: Sun, Babu, and Palomar (2014); Sun, Babu,
and Palomar (2015); Liu and Rubin (1995); Zhou, Liu, Kumar, and Palomar
(2019); Pascal, Ollila, and Palomar (2021).
