I am trying to calculate malmquist productivity index with two inputs (I_cp I_rs) and one output (O_tgs), but when I typed malmq I_cp I_rs=O_tgs, ort(I) period(year) the stata mentions that the syntax is invalid.
Does anyone knows why it happens?
regards
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Apparently your problem is occurring because you did not install the "malmq.ado" file.
