WebUnder the assumption of normally distributed disturbances, the null distribution of the Durbin-Watson statistic is the distribution of a linear combination of chi-squared variables. The p-value is computed using the Fortran version of Applied Statistics Algorithm AS 153 by Farebrother (1980, 1984). This algorithm is called "pan" or "gradsol". WebApr 9, 2024 · Interpret the results of the Durbin-Watson test by examining the test statistic and the associated p-value. 1. Fit a Linear Regression Model in R ... The Durbin-Watson test statistic (DW) is a value between 0 and 4 that measures the degree of autocorrelation in the residuals. The value DW is interpreted as follows:
