%description
Implements high-dimensional multivariate regression by stacked
generalisation (Rauschenberger 2021 <doi:10.1093/bioinformatics/btab576>).
For positively correlated outcomes, a single multivariate regression is
typically more predictive than multiple univariate regressions. Includes
functions for model fitting, extracting coefficients, outcome prediction,
and performance measurement. If required, install MRCE or remMap from
GitHub (<https://github.com/cran/MRCE>, <https://github.com/cran/remMap>).
