WebChow tests assess the stability of the coefficients (β) in a multiple linear regression model of the form y = Xβ + ε. Chow (1960) introduces two variations: the break point and forecast tests . The break point test is a standard F test from the analysis of covariance. The forecast test makes use of the standard theory of prediction intervals.
