Hi, I am also using malmq2 in STATA17 to analyze changes in efficiency over time. I've set up the xtset for the panel id and time variable. But can't seem to successfully run the malmq2 command. I keep getting below error. r(3021) sdf_o(): 3021 class compiled at different times <istmt>: - function returned error</istmt>

Dear Choonjoo and all the members of this community : I am estimating the Malmquist Index and all works ell. My question is simple: when before using the command malmq I run ldea.do, does this do file estimate the DEA scores based on a technology with constant returns to scale, variable returns to scale or both? Many thanks Choonjoo and best regards to everyone. Happy new year

Hi Marisa, I also use DEA now for my research. Could you please tell more about how exactly we can install the most recent ado files? I mean should we put the "dea.ado" in the "ado>base>d" folder and the "ldea.ado" in the "ado>base>l" folder? How about the "malmq", did you also use it, or just with the dea.ado? I once tried to use a dataset that has 2148 dmus and weights 176 KB, but it took too long. I would really appreciate if you can share how did you manage to do the DEA with such large data....
