Randomization schedule with uneven sample distribution.

[Maria Elizabeth Mercado]

Hello, I would like to ask for help in creating a command to generate a randomization schedule for a study with 2 treatment arms but an allocation ratio of 1:2. I previously found an answer for generating permuted-block randomization scheme with blocks of 4 in this forum but the allocation was balanced at 1:1. Not sure how to do it for a different ratio and with stratification.

Have you looked at the user-written command ralloc?

ssc describe ralloc

I don't know whether there is anything that supersedes it.

Hi Joseph, I have not come across that one. I just installed it and reading the guide to the command, it looks like it's exactly what I need. Thank you very much!
