Oob prediction error mse
Web3 de jun. de 2024 · Also if one of the predictions is NaN, then the variable importance measures as well as OOB Rsq and MSE are NaN. My workaround has been to use predict.all=TRUE and then take the rowMeans with na.rm=TRUE to calculate the ensemble prediction, but this requires significant extra memory. WebAn extra-trees regressor. This class implements a meta estimator that fits a number of randomized decision trees (a.k.a. extra-trees) on various sub-samples of the dataset and uses averaging to improve the predictive accuracy and control over-fitting.

WeboobError predicts responses for all out-of-bag observations. The MSE estimate depends on the value of 'Mode'. If you specify 'Mode','Individual' , then oobError sets any in bag observations within a selected tree to the weighted sample average of the observed, training data responses. Then, oobError computes the weighted MSE for each selected tree. east chezzetcook roadWebEstimate the model error, ε tj, using the out-of-bag observations containing the permuted values of x j.
