IsIt is easy to estimate a Poisson regression model using Newton Raphsonthe Newton–Raphson Iterative Technique as it only involveinvolves one parameter (mewmu).However However, I am unable to understand that how a negative binomial regression model can be estimated using Newton Raphsonthe Newton–Raphson Iterative Technique, as it involve two parameters (mewmu and dispersion parameter alpha).Can Can anyone help me in this regard.?
