✳️ Regression analysis is a special case of Durbin-Watson model where the autocorrelation coefficient is zero. ✳️ It is not easy to discuss the autocorrelation. We shall find the sampling distribution of Durbin-Watson test statistic first. ❓How can we do❓ 1. Determine what are the factors affecting the Durbin-Watson test statistic. 2. Discuss how each factor affects the sampling distribution of Durbin-Watson test statistic. 3. Induce NEW technology - probability distribution simulator - to find the sampling distribution of Durbin-Watson test statistic. (See the “method” PowerPoint file) 🏆 🏆 🏆 In this PowerPoint file, I describe the processes of investigating that the independent variable(s) affects the sampling distribution of Durbin-Watson test statistic. 🆓 As to the software, free download on https://sites.google.com/view/dwtestsoftware or https://tinyurl.com/dwtestsoftware. ✅ Source code included. ✅ Software running video: https://youtu.be/hDt1fxhrfaw 🔆 Seek cooperation!!!!!!
