Hi. I am trying to run the flexpaneldid command with CEM matching, but am running into the error r(111) "_h not found". However, none of the corresponding r(111) errors hold here - this is not a variable name, the variables are not out of order, etc. In addition, the on running the CEM option, I get 0 matched strata (1 below). However, I do not run into either of these problems if I run the flexpaneldid with the statmatching option, or if I run a regular CEM command outside of flexpaneldid. While running a regular CEM command on the same dataset, while I do get matched strata, I get 0s across the min-max columns (2 below).
I am new to both the flexpaneldid and the CEM command and would greatly appreciate it if someone could help me make sense of this.
