Hi, from the CT6 tuorial videos a MGF is given as (5-4e^t)^-1. Now i can recognise that this is a MGF for a negative binomial but I am finding it difficult to work the solution to the parameters; i.e. what does p,q and k equal to. Any help will be greatly appreciated !
Take a factor of 5 out: \([5(1-0.8e^t)]^{-1} = 0.2(1-0.8e^t)^{-1}\) Hence \(p=0.2\), \(q=0.8\) and \(k=1\).
