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
the descriptions of the negative binomial distribution that I am familiar with
do not mention theta as being a parameter of the distribution. I noticed that
when one runs the glm.nb function to perform a negative binomial regression one
obtains a value for theta. This leads to two questions
1. Is the theta required by the power_NetativeBinomial function the theta
that is produced by the glm.nb function
2. What is theta, and how does it relate to the parameters of the negative
binomial distribution?
Thank you,
John
