brant test STATA 16

[Ellie Konto]

Hi everyone

I can't run brant, detail in STATA 16. I have downloaded the oparallel and been trying to run after the omodel logit but this messege appears "the command brant is unrecognized
r(199);"
Any ideas how to solve this please?
Thank you in advance
Ellie

seems to me to imply that oparallel (from SSC, as you are asked to explain) offers a Brant test through its brant option.

If you want to use a brant command, you need to install that separately, which explains that error message.

Do

findit spost13_ado

and install the programs. You will get brant and numerous other useful routines.

I highly recommend the Long and Freese book which discusses spost13 and the underlying statistical principles:
