goodness of fit

the degree to which values predicted by a model agree with empirically observed values. For example, a researcher may wish to assess whether a pattern of frequencies from a study is the same as theoretically expected, whether two categorical variables are independent, or whether a regression equation correctly predicts obtained data. A small, nonsignificant value from a statistical goodness-of-fit test indicates a well-fitting model.
