WebThe calculator will compute power or precision, as a function of cluster size or number of clusters, for a wide variety of designs and correlation structures. We illustrate the … WebThe SHINYCRT web app has multiple features and allows substantial flexibility in specifying a design, but also has some limitations. First, methods for binary and count outcomes use a normal approximation; thus, the magnitude of time effects on power cannot be accommodated. Second, only identity link functions are allowed; thus, when the ...
