This is why the llr estimator doe...

PVAClone: new package for population viability analysis
...s feature allows comparison of any two nested or non-nested state-space models fitted using the Model Estimation procedure above - for instance one can compare the state-space Generalized Beverton-Holt model with a logistic model, even when observations are missing; - the underlying function is pva.llr can also be called repeatedly to compute profile likelihood of a parameter of interest. * Extinction Risk Estimation (under development) * - data cloning based frequentist prediction of latent variables in a general hierarchical model (Lele et al. 2010) is used to forecast future abundance time se...
