WebR 2 (coefficient of determination) regression score function. Best possible score is 1.0 and it can be negative (because the model can be arbitrarily worse). In the general case when the true y is non-constant, a constant model that always predicts the average y disregarding the input features would get a R 2 score of 0.0. WebThe coefficient of determination r2 estimates the proportion of the variability in the variable y that is explained by the linear relationship between y and the variable x. There are several formulas for computing r2. The choice of which one to use can be based on which quantities have already been computed so far.
