WebMay 30, 2013 · Hi Rick, I'm working on computing the power of the Gehan test (a generalization of the Wilcoxon Rank-Sum Test, for censored data). I need to generate two samples of the same size from two normal distributions [e.g. N(mean,std) and N(mean+loc,std)], where both samples have left-censored values, with the same amount … WebTo calculate the adjusted sample size, we divide the total expected sample size by one minus the proportion expected to dropout (0.10 in this case). We thus divide 180 by 0.9 to give a sample size adjusted for dropout of 200 in …
