Dear all,

I discovered a site where you can run R-packages in the browser (CRAN, Bioconductor). Useful when traveling. ;-)

Here the link to yesterday’s release of PowerTOST. Navigate to the bottom

Try the PowerTOST package in your browser

and change



sampleN.TOST(CV = 0.3)


      Run (Ctrl-Enter)       

to get

+++++++++++ Equivalence test - TOST +++++++++++
            Sample size estimation
Study design:  2x2 crossover
log-transformed data (multiplicative model)

alpha = 0.05, target power = 0.8
BE margins = 0.8 ... 1.25
True ratio = 0.95,  CV = 0.3

Sample size (total)
 n     power
40   0.815845

The Man pages are available as well (e.g., the one of sampleN.TOST).

Note that there is a runtime limit of 10 seconds. Hence, demanding stuff like = 0.3, n = 34, design = "2x2x4")

will not work.
