Dear Detlew,

❝ As a one-liner using the PowerTOST helper functions I got:

❝ mse2CV(mean(CV2mse(c(0.25,0.3458))))

❝ [1] 0.3011071.

❝

❝ What did the one-liner do? Calculate the intra-subject variances for T and R, calculate the mean of both and back-calculate from that mean the CV .

Sure.

❝ Or did I miss somefink Welch here?

Shame on me; was a typo – should read 0.3438…
mse2CV(mean(CV2mse(c(0.25,0.3438))))
[1] 0.2999892
