Function fit3models
fits the general (biased) random walk (GRW),
unbiased random walk (URW), and Stasis models. In addition to these three,
fit4models
also fits the model of Strict Stasis.
if silent = FALSE, a table of model fit statistics, also printed to the screen. if silent = TRUE, a list of the model fit statistics and model parameter values.
fit4models()
: add model of "Strict Stasis" to the three models
x <- sim.GRW(ns = 50, ms = 0.2)
