Dear all,
I am a R using. I have a mixed Poisson regression. my function is:
?## P(N=k)=[(a+2)/a
](lambda^k)*[((a+2/a+1)+lambda)^(-k-1)-(a+2+lambda)^(-k-1)];
lambda=a0+a1*x1+a2*x2
?and I've attached in a pdf file also.This is a poisson mixed with a
weighted exponential distribution in the case that
E(theta)=1(theta=random.effect). in fact this model is?same as a
Poisson-inverse gaussian or Poisson-lognormal regression.I want to
estimate the parameters by fitting this model on my data and then compare
with Poisson regression(glm).Which package in R can be used.
?with the best wishes
?Zamani.H
