Dear Maarten,
I really apologies for my misunderstanding. Since this command was installed
by myself( I now remember) several months ago, when I type -help diff-,
Stata gives me only one instruction. So, I take for granted that there is
only one version of DID. Sorry about this again.
My mistake because I did not read the instruction carefully. Now, I know
when I use this command I should cite as " Villa, Juan M. 2011. DIFF:
Stata Module to Perform Differences in Differences Estimation. Statistical
Software Components. Boston College Department of Economics." This is the
version I use.
Sorry for my misunderstanding of email from Maarten.
Best Regards,
Lynn Lee
