The Durbin-Watson test is used to determine if the residuals from your model have significant autocorrelation. So you look at the p-value for the test and conclude that there is ... WebWhen data set of interest is a time series data, we may want to compute the 1st-order autocorrelation for the variables of interest and to test if the autocorrelation is zero. One common test is Durbin-Watson test. The Durbin-Watson test statistic can be computed in proc reg by using option dw after the model statement.

Using simple spreadsheet functions … WebThe Durbin-Watson test statistic is defined as: ∑ t = 2 T ( ( e t − e t − 1) 2) / ∑ t = 1 T e t 2. The test statistic is approximately equal to 2* (1-r) where r is the sample autocorrelation of the residuals. Thus, for r == 0, indicating no serial correlation, the test statistic equals 2. This statistic will always be between 0 and 4.
WebThe test statistic for the Durbin-Watson test on a data set of size n is given by: D = ∑n t=2(et−et−1)2 ∑n t=1e2 t, D = ∑ t = 2 n ( e t − e t − 1) 2 ∑ t = 1 n e t 2, where et =yt−^yt e t = y t − y ^ t are the residuals from the ordinary least squares fit.
