"WebThe bootstrap method divides the data set with N cases into B samples of identical size with replacement. A separate model of some target variable is built on each of the samples, yielding an n -number of predictions for each record in the data set. The mean (average) prediction can be calculated and used as the final prediction for each record. " - Block bootstrap method
