Multimodel Inference

Model selection should be based on a well-justified criterion of what is the "best" model, and that criterion should be based on a philosophy about models and model-based statistical inference, including  ...  There is a clear philosophy, a sound criterion based in information theory, and a rigorous statistical foundation for AIC.  ...  Model selection (variable selection in regression is a special case) is a bias versus variance trade-off, and this is the statistical principle of parsimony.  ...

Inference for SDE Models via Approximate Bayesian Computation

Umberto Picchini
2014 Journal of Computational And Graphical Statistics  
Simulation studies for a pharmacokinetics/pharmacodynamics model and for stochastic chemical reactions are considered and a MATLAB package implementing our ABC-MCMC algorithm is provided.  ...  The relevance of this class of models is growing in many applied research areas and is already a standard tool to model e.g. financial, neuronal and population growth dynamics.  ...  Therefore a trade-off is necessary, namely select a small δ * while retaining a long enough sequence of draws to allow accurate posterior inference.  ...
