He made major contributions to optimal control theory and its application to stochastic economic systems. His doctoral dissertation at the University of Chicag…

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.

Webthe present analysis is concerned with the Chow statistic for individual observations rather than sums, and it will therefore involve extreme value theory. Another related test that is used in econometrics is the CUSUMSQ test based on the statistic: CUSQt,T = √ T P t s=k ε˜ 2 P s T s=k ε˜ 2 s − t−k T−k!, (9) The Chow test (Chinese: 鄒檢定), proposed by econometrician Gregory Chow in 1960, is a test of whether the true coefficients in two linear regressions on different data sets are equal. In econometrics, it is most commonly used in time series analysis to test for the presence of a structural break at a period which can be assumed to be known a priori (for instance, a major historical event such as a war).
