st: zero-inflated Poisson distribution fitting for correlated count data
I'm trying to determine the parameters of a distribution of a time-series of
yearly number of disease cases over a 33 year period. The series has many
zero values, and the variance is much larger than the mean (var=13.6,
mean=1.6). Since the data is taken from one city over a number of years,
serial correlation may be expected.
My goal is to determine the probability of x number or greater cases in any
given year, given the entire series.
I'm looking for something like -nbfit- for correlated data. Or -nbreg-
(with independent variables, like year) for correlated data.
