  • Cluster longitudinal RCT power calculations with unequal number of clusters across across experimental groups

    Hello,

    I want to compute power calculations for a cluster RCT with a baseline and 3 follow-ups.

    The number of clusters in the treatment is different to the number in the control group. Assume the sample size in the treatment and control group is the same.

    Since I have a large ICC, I want to use a command that allows to compute the MDE and account for the fact that I have 3 follow-ups. Eventually, I would like to simulate what would happen to the MDE if I include additional waves.

    Does anyone know a command that facilitates this task ?

    Thanks !
