Webportant issue in statistics. The earliest references go back to Chow [9] and Quandt [33]. Chow’s test is to assume that the time of structural change is known a priori, and the critical values for the χ2 distribution can be simply used. Quandt’s test is to take the largest Chow test statistic over all possible times of the structural change.
