perturb.params

Takes a baseline set of parameters and perturbs it to
 create a variety of starting points for maximum likelihood
 estimation or MCMC

optimize

Auxiliary functions and data sets for "Ecological Models and Data", a book presenting maximum likelihood estimation and related topics for ecologists (ISBN 978-0-691-12522-0).
