Durbin watson test r package

P-values in Durbin-Watson test obtained through the use of functions available in packages "lmtest" and "car" are different. The difference is quite significant. function "dwtest" in "lmtest" is much faster than "burbinwatson" in "car". Actually, you can take a nap while the latter trying to calculated Durbin-Watson test. The Durbin Watson test reports a test statistic, with a value from 0 to 4, where the rule of thumb is: 2 is no autocorrelation. 0 to 2 to 4 is negative autocorrelation (less common in time series data). statistic the value of the test statistic. dublin2009.com the p-value of the test. parameter degrees of freedom. method a character string indicating what type of test was performed. dublin2009.com a character string giving the name(s) of the data.

[R] Durbin-Watson test in packages "car" and "lmtest". Torsten Hothorn Torsten. Hothorn at dublin2009.com Fri Apr 19 CEST. I'm trying to obtain the Durban Watson statistic for a regression I'm running in R. However, when I run the code dublin2009.com(x~y), R keeps telling me Error: could not find function "dublin2009.com". I've checked and the dublin2009.com function is part of the bstats package, which is a base package. The Durbin Watson test reports a test statistic, with a value from 0 to 4, where the rule of thumb is: 2 is no autocorrelation. 0 to 2 to 4 is negative autocorrelation (less common in time series data). Durbin-Watson Test Description. Performs the Durbin-Watson test for autocorrelation of disturbances. Usage. Arguments. Either a vector z or a formula with a single explanatory variable like ~ z. Details. The Durbin-Watson test has the null hypothesis that the autocorrelation Value. P-values in Durbin-Watson test obtained through the use of functions available in packages "lmtest" and "car" are different.
