Table 4

Comparison of model fit criteria of ZIP and ZINB models.

Criterion	ZIP	ZINB
Scaled Pearson	3.4216	2.4309
Full log likelihood	−144381.3621	−118910.3002
AIC	288836.7242	237890.6003
BIC	289194.1387	238228.6952

Note. ZIP = zero-inflated Poisson.
ZINB = zero-inflated negative binomial.
AIC = Akaike Information Criterion.
BIC = Bayesian Information Criterion.
