%description
Weighted-ensemble regression over base learners supported by 'caret' (Kuhn
(2008) <doi:10.18637/jss.v028.i05>), with cross-validated hyperparameter
selection, out-of-fold diagnostics, and signed residual- offset estimates.
Multi-response problems use iterative input-space expansion related to
Spyromitros-Xioufis et al. (2016) <doi:10.1007/s10994-016-5546-z>, with
Jacobi or 'Gauss-Seidel' sweeps, package-defined companion gates and
per-response iteration stitching. A package-defined pseudo-label stage
promotes prediction rows by a cross-model and cross-dataset range ratio
and accepts rounds with an out-of-fold squared-correlation gauge.
