Hello, I am trying t use the command pbalchk to examine the balance of covariates with ipw weights. A shortened version of the model is below..daetaex would not accept all the variables becuase it was too many. I keep getting a error that pbalchk will not accept factor variables. Can you advise? Is it possible to use pbalchk and specify factor variables?


pbalchk pt_nopt ib0.agecat ib0.sex ib0.urb_rural ib0.insur_cat ib0.high_dprc , wt(ipt_wt)
