Dear Helmut!

Beg me pardon, seems a copy-paste devil:

CV 0.07 split based on the SE ratio: 0.0886 0.0442

 variances: 0.00782 0.00196 ratio: 4

 standard errors: 0.0807 0.0571 ratio: 2 (?)


What about:
library(PowerTOST)
CV    <- 0.07
ratio <- 2    # ratio of se's
# ratio of variances is simply ratio of se's squared
r1  <- CVp2CV(CV=CV, ratio=ratio^2)
CV2se(r1)


Gives standard errors:
[1] 0.0884356 0.0442178

Regards,

Detlew
