Fit Models

jModelTest is a tool to carry out statistical selection of best-fit models of nucleotide substitution. It implements five different model selection strategies: hierarchical and dynamical likelihood ratio tests (hLRT and dLRT), Akaike and Bayesian information criteria (AIC and BIC), and a decision...

Second release of Linstats, a toolbox for building, testing and making statistical inferences from linear models. There are many features in this toolbox that are not available in the matlab statistical toolbox including n-way ANACOVA and n-way MANOVA as well numerous diagnostic plots. There is...

This toolbox was designed to simulate and fit linear state space models. The main literature I used for this particular package is Kim and Nelson (1999). A state space model (without non stochastic coefficients) is given by:y(t)=beta(t)*x(t)'+e(t)...
