How do I now extract the stored standard deviations for the 2 means, so I can divide the difference in means by the pooled standard deviation? I used lincom to obtain the difference in means from the svy post-estimation results. Then obtained the standard deviations for each means (as the SE is reported by svy: means) I calculated the means by treatment/control groups. The purpose is to evaluate differences before and after propensity score weighting (not matching so I cannot use PSMATCH2 or other similar packages). I am comparing the means of 2 groups (Y: treatment and control) for a list of X predictor variables. I need to calculate the standardized bias (the difference in means divided by the pooled standard deviation) with survey weighted data using STATA.
