Sample Size and CV for Replicate Design [Power / Sample Size]
Dear EM,
Thank you for your reply. I downloaded the package and indeed I see the 2x2x4 design is supported. However, given the information I have available and my ultimate goal, I'm not sure how to specify what I need. I see targetpower=0.80 and alpha=0.05, as well as a few other arguments such as CV and theta. Do I have enough information in what I posted in the initial post to solve my problem using PowerTOST? I should mention I've never used the CV metric before, and I don't see an argument to specify both the 0.35 and 0.30 numbers. Are these values some how related to the 'theta' values that I'm also asked to specify?
Thank you so much.
