WebTechnically, ordinary least squares (OLS) regression minimizes the sum of the squared residuals. In general, a model fits the data well if the differences between the observed values and the model's predicted values are small and unbiased. Before you look at the statistical measures for goodness-of-fit, you should check the residual plots. http://www.vassarstats.net/csfit.html
