Sample size calculation using one sided test with power command

[Karl Yesler]

Hello all,

I am trying to run a test to determine the sample size where the outcome is proportions and has repeated measures. I would like to conduct a one-sided test however, I do not see any options to do so using the power command. I was wondering whether there is a way to do so? Here's my code.

power repeated .6 .5, corr(0.7) varerror(.2)

Also, I was wondering, it's odd that this command does not require input on how many repeated observations for clusters are requested?

Thanks in advance!
