Calibrar: an R package for fitting complex ecological models
1. The fitting or parameter estimation of complex ecological models is a challenging optimization task, with a notable lack of tools for fitting complex stochastic models. 2. calibrar is an R package that has been developed for fitting complex ecological models to data, including complex Individual Based Models. It is a generic tool that can be used for any type of model, especially those with ...
متن کاملeco: R Package for Ecological Inference in 2x2 Tables
eco is a publicly available R package that implements the Bayesian and likelihood methods proposed in Imai, Lu, and Strauss (Forthcominga) for ecological inference in 2×2 tables as well as the method of bounds introduced by (Duncan and Davis, 1953). The package fits both parametric and nonparametric models using either the Expectation-Maximization algorithms (for likelihood models) or the Marko...
متن کاملIntroducing untb, an R Package For Simulating Ecological Drift Under the Unified Neutral Theory of Biodiversity
The distribution of abundance amongst species with similar ways of life is a classical problem in ecology. The unified neutral theory of biodiversity, due to Hubbell, states that observed population dynamics may be explained on the assumption of per capita equivalence amongst individuals. One can thus dispense with differences between species, and differences between abundant and rare species: ...
متن کاملmizer: an R package for multispecies, trait-based and community size spectrum ecological modelling
Size spectrum ecological models are representations of a community of individuals which grow and change trophic level. A key emergent feature of these models is the size spectrum; the total abundance of all individuals that scales negatively with size. The models we focus on are designed to capture fish community dynamics useful for assessing the community impacts of fishing.We present mizer, a...
متن کاملAn R package for state-trace analysis.
State-trace analysis (Bamber, Journal of Mathematical Psychology, 19, 137-181, 1979) is a graphical analysis that can determine whether one or more than one latent variable mediates an apparent dissociation between the effects of two experimental manipulations. State-trace analysis makes only ordinal assumptions and so, is not confounded by range effects that plague alternative methods, especia...
