loglik.dmm {drimmR}R Documentation

Evaluate the log-likelihood of a drifting Markov Model

Description

Evaluate the log-likelihood of a drifting Markov Model

Usage

## S3 method for class 'dmm'
loglik(x, sequences, ncpu = 2)

Arguments

x

An object of class dmm

sequences

A character vector or a list of character vectors representing the sequence

ncpu

Default=2. Represents the number of cores used to parallelized computation. If ncpu=-1, then it uses all available cores.

Value

A list of log-likelihood (numeric)
