In these small samples, leave-one-out cross-validation (LOOCV), 10-fold cross-validation (CV) and the .632+ bootstrap have the smallest bias for diagonal discriminant analysis, nearest neighbor and classification trees.

With a focus on prediction assessment, we compare several methods for estimating the ‘true’ prediction error of a prediction model in the presence of feature selection.

We hope for this issue to be resolved shortly. The .632+ bootstrap is quite biased in small sample sizes with strong signal-to-noise ratios.

MSE is a risk function, corresponding to the expected value of the squared error loss or quadratic loss. LOOCV and 10-fold CV have the smallest bias for linear discriminant analysis.
