<P> In statistics, the coefficient of determination, denoted R or r and pronounced "R squared", is the proportion of the variance in the dependent variable that is predictable from the independent variable (s). </P> <P> It is a statistic used in the context of statistical models whose main purpose is either the prediction of future outcomes or the testing of hypotheses, on the basis of other related information . It provides a measure of how well observed outcomes are replicated by the model, based on the proportion of total variation of outcomes explained by the model . </P>
