test.var.het

Test for heterogeneity of variances among samples in a time-series

Facilitates analysis of paleontological sequences of trait values.
Functions are provided to fit, using maximum likelihood, simple
evolutionary models (including unbiased random walks, directional
evolution,stasis, Ornstein-Uhlenbeck, covariate-tracking) and
complex models (punctuation, mode shifts).
