Hi Victor,

I tried to reconstruct your original post as good as I could. Since it was broken before the first “\(\mathcal{A}\)”, I guess you used an [image] UTF-16 character whereas the forum is coded in [image] UTF-8. Please don’t link to large images breaking the layout of the posting area and forcing us to scroll our viewport. THX.

I think that your approach has same flaws.

library(PowerTOST)
design <- "2x2x2" # for others, see known.designs()
n      <- 24
CV     <- 0.25
PE     <- 0.95
alpha  <- power.TOST(CV = CV, n = n, theta0 = 1.25, design = design)
beta   <- 1 - power.TOST(CV = CV, n = n, theta0 = PE, design = design)
cat("alpha =", alpha,
    "\nbeta  =", beta, "\n"


Gives
alpha = 0.04999527
beta  = 0.2608845
