How we generate random variates from a generalized poisson distribution?

Dear all, I want to use generate draws from the "generalized poisson distribution". Is there any function in matlab to do that?

thanks

Dear all,

any suggestion?

If you have the Statistics and Machine Learning Toolbox, that is one of the distributions given in the random() function. From the help:

Generate a single random value from Poisson distributions with rate parameters 1, 2, ..., 6, respectively:
x2 = random('Poisson',1:6,1,6)
x2 =
   0   0   1   2   5   7

The generalized poisson model assumes GP(lamba, phi) where lamba is the mean and phi is a dispersion parameter. So according to the above function I have

 M=poissrnd(lamda)

 x2 = random(M,phi,1,1)

Is that correct?. If you could give me a more specific example for my case that would be great.

Many thanks
