The coefficient of determination is used in the context of statistical models
whose main purpose is the prediction of future outcomes on the basis of other
related information. It is the proportion of variability in a data set that
is accounted for by the statistical model. It provides a measure of how well
future outcomes are likely to be predicted by the model.
The R^2 coefficient of determination is a statistical measure of how well the
regression approximates the real data points. An R^2 of 1.0 indicates that the
regression perfectly fits the data.
