摘要: Ecological counts data are often characterized by an excess of zeros and spatial dependence. Excess can occur in regions outside the range dis- tribution a given species. A zero-inflated Poisson regression model is developed, under which species determined probit model, including physical variables as covariates. Within that range, independently drawn from distribution whose mean depends on biotic variables. Bayesian inference for this illustrated using oak seedling counts.
