Mean squared error (MSE) of estimates, model error (ME), mean of the number of selected covariates (NONZERO), prediction model errors (PE), mean prediction squared errors (MPSE), mean number of the false positives (FP) and false negatives (FN), the number of selected covariates among identical covariates in the model () and the probability of correctly eliminated identical covariates (prob).
