Plugging the p (the success probability) and the r (the number of
successes until the experiment is stopped) from the Wikipedia article
Colleagues,
I want to use the power_NetativeBinomial function from the PASSED library. The
function requires a value for a parameter theta. The meaning of theta is not
given in the documentation (at least I can�t find it) of the function. Further
