Mata command not found

[Guillaume Pousse]

Hi all,

I am using the "two_side" user written package - open source from https://www.princeton.edu/~honore/stata/ - as part of a replication project of the Bazzi (2017) AER paper.

The two_side.ado contains a line "mata: two_sidemata("`varlist'","`touse'",`estmet',`print details', `boots')" which prompts the following error message from my STATA (MP18) when the script tries to run the two_side command

"<istmt>: 3499 two_sidemata() not found
r(3499)".

I have all three "two_side.ado, two_side.shlp, and ltwo_side.mil" in the relevant ado folder, as well as having the relevant ado folder stored as an adopath. I am not sure where this issue may be coming from and am not very familiar with STATA's mata language.

Thanks in advance for any help!

I have all three "two_side.ado, two_side.shlp, and ltwo_side.mil" in the relevant ado folder . . .

According to the help files, a Mata library must have the file name suffix of .mlib.

Try renaming the file ltwo_side.mil to ltwo_side.mlib and see whether that helps.

Also, try

mata : mata mlib index

before running the command.
