## S4 method for signature 'fitsir'
dispersion(object, dist = c("quasipoisson", "nbinom",
  "nbinom1"))

`object`	fitsir object
`dist`	distribution

quasipoisson returns the sum of pearson residuals divided by the degrees of freedom. nbinom assumes quadratic mean-variance relation (var=mu+mu^2/k) and estimates k based on maximum likelihood. nbinom1 assumes linear mean-variance relation (var=(1+phi)mu) and estimates phi based on maximum likelihood.
