The zero-inflated Poisson variant is preferable to the negative binomial variants of the N-mixture, as it models an ecological mechanism rather than a statistical phenomenon and generates reasonable parameter ...
Specifically, we assess the statistical fit with AIC and assess the ecological realism by comparing the parameter estimates with expected values derived from literature, ecological theory, and expert opinion ...
Statistical models like the negative binomial variants of the N mixture, that model statistic properties of data and not ecological mechanisms, are susceptible to unexpected and erroneous parameter estimation ...
