Dear Professor Clément de Chaisemartin,
I hope this message finds you well. I am encountering an issue with a DID (Difference-in-Differences) program and would greatly appreciate your insights.
Commands Used: I am running a series of DID analyses with the following commands:
Issue Description: I am conducting a DID analysis with five policy variables, where each command tests the effect of one policy variable as the treatment variable while controlling for the other four policy variables. The commands for "SentN_compete_did," "SentN_supply_did," "SentN_environment_did," and "SentN_notmention_did" execute successfully without errors (last four lines), even when control variables are included. However, when I run the command for "SentN_defense_did" (first line), I encounter an error message "inv_Denom_4_XX not found." And it is important to note that if I run the command for "SentN_defense_did" without any control variables, it runs successfully and produces results.
I have attempted to troubleshoot this issue over several days, including trying different computers, yet the error persists. I could share the data and relevant code with you if you need. Could you please spare some time to review the question and provide insight into what might be causing this issue? Your assistance in resolving this matter would be immensely valuable to me.
Thank you very much for your time and support.
Best regards,
