Panel Data Analysis, selecting between, pooled OLS, RE and FE

WebUnder the null, both the sigma from the RE estimation and the sigma from the FE estimation are consistent. The formula for the vcv uses sigma. For example, in a RE estimation you automatically use the RE sigma in the vcv. But there is nothing stopping you from replacing it with the FE sigma and getting a slightly different, but also consistent ... WebThe Hausman test can be used to differentiate between fixed effects model and random effects model in panel analysis. In this case, Random effects (RE) is preferred under the null hypothesis due to higher efficiency, while under the alternative Fixed effects (FE) is at least as consistent and thus preferred. the green perth https://academicsuccessplus.com

Consider the linear model y = Xb + e, where y is the dependent variable and X is vector of regressors, b is a vector of coefficients and e is the error term. We have two estimators for b: b0 and b1. Under the null hypothesis, both of these estimators are consistent, but b1 is efficient (has the smallest asymptotic variance), at least in the class of estimators containing b0. Under the alternative hypothesis, b0 is consistent, whereas b1 isn't.

WebThe Hausman test The Hausman test statistic The Hausman test statistic is defined as m = q′(var ^FE var ^RE) 1q; with q = ^FE ^RE. Under RE, the matrix difference in brackets is positive, as the RE estimator is efficient and any other estimator has a larger variance. The statistic m is distributed ˜2 under the null of RE, with degrees WebStata's xtreg random effects model is just a matrix weighted average of the fixed-effects (within) and the between-effects. In our example, because the within- and between-effects are orthogonal, thus the re produces the same results as the individual fe and be. With more general panel datasets the results of the fe and be won't necessarily add ...
