Using ralloc to generate allocation table, unequal groups

[mike p]

I am trying to generate an allocation table for use in REDCap, but am struggling with the ralloc command.

Allocation requirements:

3 treatment groups (control, baseline, intervention)

• group sizes will be equivalent to 100, 200, 200, respectively.
• If n < 500, allocation should still meet the ratio above

Stratified by Gender (male, female, other - 1:1:1) and Age (5 age groups - 1:1:1:1:1)

Can anyone give me any guidance?
