It estimates the fraction of the variance in Y that is explained by X in a simple linear regression. So if we have the observed dataset {y1,...yn} and the fitted dataset {f1,...fn}, and we denote the fitted dataset {f1,...fn} with {y1,...yn}, then as a starting point the total variation in the Yi around their average value can be decomposed as follows
