%description
Contains an implementation of 'StabilizedRegression', a regression
framework for heterogeneous data introduced in Pfister et al. (2021)
<arXiv:1911.01850>. The procedure uses averaging to estimate a regression
of a set of predictors X on a response variable Y by enforcing stability
with respect to a given environment variable. The resulting regression
leads to a variable selection procedure which allows to distinguish
between stable and unstable predictors. The package further implements a
visualization technique which illustrates the trade-off between stability
and predictiveness of individual predictors.
