Summary statistics of five distribution models of county population counts within each census (year).

size is the number of counties. lik_max is the approximate maximum likelihood of the Tweedie model. aicc_xxx gives the AICc of the Tweedie model (xxx = tweedie) and of each of the other four distributions models: log series distribution (xxx = logseries), negative binomial distribution (xxx = negbinom), Poisson-lognormal distribution (xxx = poilog), and Zipf distribution (xxx = zipf). wt_xxx gives the AICc weight of each of the five distribution models.
