# Stage-wise sample size

For a multi-stage design, __multiarm__ requires a choice about the total stage-wise sample size.
This can be either fixed (the sample size in each stage should be a common fixed value, regardless of the number of treatments present), or variable (the sample size in each stage should be allowed to vary, according to the number of treatments present).
Specify your chosen type of stage-wise sample size here.
