I found a do file online where a very renowned economist used "myqreg2" command while estimating quantile gender wage gaps (so far I understand). I tried to rerun the command in my stata16 software that says, "command myqreg2 is unrecognized, last estimates not found". The search command also came out with same results as the google search did. ssc install myqreg2 also came up with a refusal.

Now, my question is "Is there any such command is Stata? If not, what is the correct command in this case?"

Thanks in advance for your answer?
