How to get mean square error in a quick way using Matlab?

WitrynaPlotting the cumulative loss allows you to monitor how the error changes as the number of predictor trees in GAM increases. Find the minimum error and the number of predictor trees used to achieve the minimum error. [M,I] = min (L_noInteractions) M = 0.0655 I = 23 The GAM achieves the minimum error when it includes 22 predictor trees.
