Hi everyone, I understand you can use the macro %psmatch. However, I installed a lower version of sas and I cannot use the psmatch macro. I found another one called "psmatch_multi" from https://support.sas.com/resources/papers/proceedings17/0812-2017.pdf My problem is that I need to match by group. For example, I want to match the treatment and control sample by gender, or by age, that is, the treatment and control will have the exact gender by age. Can someone help me on this issue? by using the psmatch_multi macro. Or, if you have other method, that would also be great(only propensity score matching). Thanks a lot!
