Analysis of evoltuionary time-series

Description

This package includes a variety of functions useful for analyzing evoltuionary time-series, particularly for paleontological data. The functions are useful for analyzing sequences in terms of statistical models, with three models implemented: directional evolution (modeled as a general random walk), unbiased random walks, and stasis. These analyses are outlined in Hunt (2006).

Examples

 x <- sim.GRW(ns=30, ms=0, vs=.3)       # simulate unbiased random walk
 fit3models(x)          # compare fits of directional, random walk, and stasis models
