by()andabsorb()are allowed and can be combined. givregressdoes a small sample adjustment (small) automatically. givregressdoes not exit with error if covariates are collinear with the dependent variable. If thegivregressmodel is not identified, standard errors and coefficients are set to missing...
It may be a good idea to center the variable (by subtracting the mean) before squaring it. Here we run summarize using quietly to suppress the output and retrieve the mean from the stored result r(mean): quietly summarize setting gen settingcsq = (setting - r(mean))^2 / Stata will ...
When the match is not exact, a parametric model must be used to control for the differences in the covariates across treated and control groups. This may be a linear regression, a maximum likelihood estimator or some other estimator. Applying a matching method to the data before analysis can ...
