I encountered the below warning message when I used version 6 which is posted on Github but didn't have such an issue when I used version 5.7.3 13nov2019 (installed through SSC). The standard error of the estimated coefficient (on DummyX in this case) is not reported when this warning is presented. Do you have any idea why it happens and how to solve it? Any suggestion will be highly appreciated!
