%description
Large-scale matrix-variate data have been widely observed nowadays in
various research areas such as finance, signal processing and medical
imaging. Modelling matrix-valued data by matrix-elliptical family not only
provides a flexible way to handle heavy-tail property and tail
dependencies, but also maintains the intrinsic row and column structure of
random matrices. We proposed a new tool named matrix Kendall's tau which
is efficient for analyzing random elliptical matrices. By applying this
new type of Kendell’s tau to the matrix elliptical factor model, we
propose a Matrix-type Robust Two-Step (MRTS) method to estimate the
loading and factor spaces. See the details in He at al. (2022)
<arXiv:2207.09633>. In this package, we provide the algorithms for
calculating sample matrix Kendall's tau, the MRTS method and the Matrix
Kendall's tau Eigenvalue-Ratio (MKER) method which is used for determining
the number of factors.
