How to calculate power correctly? [Power / Sample Size]
Hi All,
Let's say I have the followind results after typical BE-study:
n=30, CV=0.20, ratio=0.97, UL=1.02 and LL=0.92
if I want to calculate power using default settings of PowerTOST I see:
If to add ratio I have:
If to use also limits of CI result the result is:

Do I use formulas correcly and which option is better?

if I want to calculate power using default settings of PowerTOST I see:
power.TOST(CV=0.20, n=30)
[1] 0.948603
If to add ratio I have:
power.TOST(CV=0.20, n=30, theta0=0.97)
[1] 0.9781158
If to use also limits of CI result the result is:
power.TOST(CV=0.20, n=30, theta0=0.97, theta1=0.92, theta2=1.02)
[1] 2.334844e-05

Do I use formulas correcly and which option is better?
