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 me… WebR-squared intuition. When we first learned about the correlation coefficient, r r, we focused on what it meant rather than how to calculate it, since the computations are lengthy and computers usually take care of them for us.
