Impact of Regressand Stratification in Dataset Shift Caused by Cross-Validation
Data that have not been modeled cannot be correctly predicted. Under this assumption, this research studies how k-fold cross-validation can introduce dataset shift in regression problems. This fact implies data distributions in the training and test sets to be different and, therefore, a deteriorati...
