Hi Helmut,

❝ sampleN.TOST(alpha=0.0294, CV=CV, theta0=0.95, targetpower=0.8, design="2x2x2")

Agree with every bit of your post. Though, technically I wonder if the above function call is approximative due to the lacking subtraction of a DF.
Perhaps there'd be a point in updating the package to allow for curious people and nitpickers to specify if the call forms part of a two-stage approach and needs internal subtraction of a DF.
This of course a technical digression and I apologise for borderline hijacking JJ's thread now.
