And then test the joint hypothesis . The command can test for statistically significant differences between either one control group and all other groups or between all groups against each other. 1. Accessing Stata The statistical package Stata can be found at the OCSS (Office of Computing and Communications for Social Sciences) lab, located at the 212 Lincoln Hall. Logistic Regression with Stata Chapter 2 - OARC Stats First, we manually calculate F statistics and critical values, then use the built-in test command. Hi! See -help test- if you are not familiar with it. I'm talking about F = ( (SS Residual restricted - SSR unrestricted ) / (df restr - df unrestr)) / (SSR unrestr/ (n-k-1)) How to Interpret the F-test of Overall Significance in Regression ...

To test the joint significance of two or more covariates, you type: test lninvgr lnconsgr lnproduc. For example, the estat hettest command uses a chi-square to determine the likelihood of heteroskedasticity in a regression model. Stata will list the components of the hypothesis being tested. So, in my current research project, I have to test the relationship of certain variables using spatial econometrics. A. Response to question: Of course it does: the variance-covariance matrix in in the middle of the Wald test statistic forumula, and the robust version is the right one to use if there's hetroskedasticity.. It's easy enough to verify for yourself: sysuse auto, clear regress price weight foreign mpg estat hettest test weight foreign mpg regress price weight foreign mpg, robust test weight foreign mpg
