stateDec {countHMM}

stateDec

Description

Decodes the states of the Markov chain underlying the observed time series of counts using the Viterbi algorithm. For details, see Zucchini et al. (2016).

Usage

stateDec(mod)

Arguments

mod

An object of type countHMM (as returned by the function fitMod).

Value

A vector of Viterbi-decoded states.
