Reg vce robust
Tīmeklis使用vce(robust)参数后，回归结果中的系数和标准误都是异方差稳健的，并且t值和p值也已经经过了调整。 总结： 通过Breusch-Pagan-Godfrey检验或White检验可以检验异方差问题，如果存在异方差问题，可以使用异方差稳健标准误或异方差稳健回归来解决。 http://rostestlatvia.com/ce-certificate/

TīmeklisTo reproduce the Stata default behavior of using the robust option in a call to regress you need to request vcovHC to use the HC1 robust variance-covariance matrix. Read more about it here. The following example that demonstrates all the points made above is based on the example here.
