Hi Helmut,

Let me understand again by looking following framework,
Following data is available with me,
Target power : eg, 0.8, .85, 0.9, CwT,CwR,sigWT,SigWR,theta0,theta1,theta2.
i want to estimate sample size for low to moderate NTID. Also to estimate sample size by assuming 30 & 40 % dropout rate.
I have gone through the examples. Sometimes error comes as its beyond implied limit. Heteroscedasticity can be challenging for me as T>R.

Can you check and verify if i am using correct programming. This Example.
