%description
Covariance Regression with Random Forests (CovRegRF) is a random forest
method for estimating the covariance matrix of a multivariate response
given a set of covariates. Random forest trees are built with a new
splitting rule which is designed to maximize the distance between the
sample covariance matrix estimates of the child nodes. The method is
described in Alakus et al. (2023) <doi:10.1186/s12859-023-05377-y>.
'CovRegRF' uses 'randomForestSRC' package (Ishwaran and Kogalur, 2022)
<https://cran.r-project.org/package=randomForestSRC> by freezing at the
version 3.1.0. The custom splitting rule feature is utilised to apply the
proposed splitting rule. The 'randomForestSRC' package implements 'OpenMP'
by default, contingent upon the support provided by the target
architecture and operating system. In this package, 'LAPACK' and 'BLAS'
libraries are used for matrix decompositions.
