Description
hausman performs Hausman's specification test. To use hausman, perform the following steps.
(1) obtain an estimator that is consistent whether or not the hypothesis is true;
(2) store the estimation results under name-consistent by using estimates store;
(3) obtain an estimator that is efficient (and consistent) under the hypothesis that you are testing, but
inconsistent otherwise;
(4) store the estimation results under name-efficient by using estimates store;
(5) use hausman to perform the test
hausman name-consistent name-efficient [, options]
The order of computing the two estimators may be reversed. You have to be careful, though, to specify to hausman the models in the order "always consistent" first and "efficient under H0" second.
It is possible to skip storing the second model and refer to the last estimation results by a period (.).
看帮助或者手册,hausman后面的次序是不能反了的。
你先需要把计量理论高清楚
fe的估计在H0的假设下 是 一致估计量,但不是有效的
re的估计在H0的假设下是有效估计量,但不是一致的
