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
