WebYes. The Durbin-Watson test assesses the autocorrelation of residuals of a linear regression fit. The function dwtest () expects you to either supply a fitted lm object or equivalently the corresponding formula plus data. The implementation in dwtest () only allows to test lag 1. If you want to test more lags I would recommend using bgtest ... WebThe Durbin-Watson test has the null hypothesis that the autocorrelation of the disturbances is 0. It is possible to test against the alternative that it is greater than, not equal to, or less than 0, respectively. This can be specified by the alternative argument. Under the assumption of normally distributed disturbances, the null distribution ...
