strat_sample_folds

internal

Extends the mlr3 machine learning framework with
spatio-temporal resampling methods to account for the presence of
spatiotemporal autocorrelation (STAC) in predictor variables. STAC may
cause highly biased performance estimates in cross-validation if
ignored. A JSS article is available at <doi:10.18637/jss.v111.i07>.
