R is a measure of the goodness of fit of a model. In regression, the R coefficient of determination is a statistical measure of how well the regression predictions approximate the real data points. An R of 1 indicates that the regression predictions perfectly fit the data. Values of R outside the range 0 to 1 occur when the model fits the data worse than the worst possible least-squares predictor (equivalent to a horizontal hyperplane at a height equal to the m… Webpower (like R-square) and goodness of fit tests (like the Pearson chi-square).

WebIn logistic regression, R-squared is typically not used because it does not provide a direct measure of model fit like it does in linear regression.
