    Quasi-poisson distribution, quantile function




    Hello,

    I am searching for a closed form representation of the quantile function for the quasi-poisson distribution. Also, if anyone knows of any papers dealing with the quasi-poisson distribution (not regression) that would be helpful as well.

    Thanks.

    Re: Quasi-poisson distribution, quantile function

    I have been google this for a while, and cannot find out a source talking about this yet. All sources seeming is just talking about specifying the dispersion parameter as a linear function of mean in GLM - therefore is just specifying the relationship between conditional mean and conditional variance, i.e. a quasi-likelihood, without the complete likelihood.

    Just curious in your setting what is assumed behind.

    Yeah I wasn't sure what was being referred to either. As far as I know there isn't an actual quasi-poisson distribution. Although you might be able to parameterize the negative binomial in a way that mimics the properties of the quasi-poisson's quasi-likelihood.
    I don't have emotions and sometimes that makes me very sad.
