✳️ regression analysis is a special case of Durbin-Watson model where the autocorrelation coefficient is zero. ✳️ the values of independent variable(s) have main impact on the sampling distribution of Durbin-Watson test statistic. This slide displays how the CLT shows in the sampling distribution in the different cases of independent variable. For the software has been released on google site, https://tinyurl.com/dwtestsoftware. ✅ Source code included. ✅ Software running video: https://youtu.be/hDt1fxhrfaw 🔆 seek cooperation!
