%description
Implements multi-study learning algorithms such as merging, the
study-specific ensemble (trained-on-observed-studies ensemble) the study
strap, the covariate-matched study strap, covariate-profile similarity
weighting, and stacking weights. Embedded within the 'caret' framework,
this package allows for a wide range of single-study learners (e.g.,
neural networks, lasso, random forests). The package offers over 20
default similarity measures and allows for specification of custom
similarity measures for covariate-profile similarity weighting and an
accept/reject step. This implements methods described in Loewinger,
Kishida, Patil, and Parmigiani. (2019) <doi:10.1101/856385>.
