Supplement 1. R scripts for fitting the base- and full-model structures to sample data.

The base model (Model structure 2) is fitted with 5 states and fixed step length (FS). The full model (Model structure 9) is fitted with 6 states and time-varying step length (TS). The script then calls Viterbi_funs.R to estimate the Viterbi sequence of states based upon the posterior state-dependent parameter estimates. Running the script requires jags software (freely available at http://mcmc-jags.sourceforge.net/) and the r package 'R2jags'. Sample data, priors, and example R2jags fitting objects are supplied in jags_data.Rd which can be directly loaded into r. The text files contain the model structures in jags script. To run the script, place all the files into your r working directory.
