Hi all -

I am applying the command from Emsley, Lunt, Pickle and Dunn (The State Journal 2018 https://journals.sagepub.com/doi/pdf...867X0800800302). "dr" command seems to work fine but the issue is independent variables, sample size as well as R-squared are not tabulated, only the "exposure" or the variable of interest/indicator is shown in the output. However, there are published papers (across all disciplines) that use this method show the complete set of results. So I wonder if I miss something or Stata per se is unable to display them. See the below example:
Only a is presented no matter which model is used.

Model 1: dr y a

Doubly Robust Estimate of the effect of a on y
Using sandwich estimator of SE

------------------------------------------------------------------------------
| Coef. Std. Err. z P>|z| [95% Conf. Interval]

a | .3269012 .0862426 3.79 0.000 .1578689 .4959335

Model 2: dr y a ybase

Doubly Robust Estimate of the effect of a on y
