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). In program evaluation, the Chow test is often used to determine … WebA tool that is particularly useful in this regard is the Chow test.

WebStep 1: Click the “Data” tab and then click “Data Analysis.”. Step 2: Click “F test two sample for variances” and then click “OK.”. Step 3: Click the Variable 1 Range box and then type the location for your first set of data. For example, if you typed your data into cells A1 to A10, type “A1:A10” into that box. WebSince Chow test is mostly used in time series, SAS has included it with proc autoreg. The way to specify the two subsets is to specify the breakpoint in terms of the position of the observations. In this example, we use proc freq to identify the position for the breakpoint and we then have to sort the data accordingly. proc freq data = hsb2 ...
