WebApr 24, 2024 · I'm rejecting the Null hypothesis based on the p-value being so small, and less than 0.0005 Does the result of the -hausman-test at 24.98 mean that the coefficients shared by -fe- and -re- specification are not that similar than because it is kind of a big number ? Appreciate the help, hopefully my inferences and understanding will be okay too Webmatrix of fitted values Xˆ, Xˆ = Z(Z′Z)−1Z′X = P ZX (5) ... 3 Durbin-Wu-Hausman Test 3.1 Idea In econometric modeling, there are often questions on endogeneity. Do we know how to test whether an independent variable is endogenous statistically? The answer is: sort of, but not really. We cannot do endogeneity test without a valid

The Hausman Test (also called the Hausman specification test) detects endogenous regressors (predictor variables) in a regression model. Endogenous variables have values that are determined by other variables in the system. Having endogenous regressors in a model will cause ordinary least … See more The Hausman test is sometimes described as a test for model misspecification. In panel data analysis (the analysis of data over time), the Hausman test can help … See more Interpreting the result from a Hausman test is fairly straightforward: if the p-value is small (less than 0.05), reject the null hypothesis.

The p value is a proportion: if your p value is 0.05, that means that 5% of the time you would see a test statistic at least as extreme as the one you found if the null hypothesis was true.
