WitrynaIf using resampling (bootstrap or cross-validation) to both choose model tuning parameters and to estimate the model, you will need a double bootstrap or nested cross-validation. In general the bootstrap requires fewer model fits (often around 300) than cross-validation (10-fold cross-validation should be repeated 50-100 times for stability).
