Issue reported from user by email:
I keep receiving the error code “option test_pair_codes() required”. I have tried running the command in many different ways, including the simplest possible specification where I simply run “iebaltab `balvars’, groupvar(treatment)” and get this error no matter which options I do or do not specify.
After investigation:
It was a coding error on my end – there was no variation in treatment status at baseline, the period at which I was testing for balance. Thanks for your help, and sorry to bother you with what turned out to be a silly mistake on my end!
While this is not an error that risk creating incorrect results, the command should test for this and provide a more helpful error message.
