forward_backward: Forward and Backward Probabilities for Hidden Markov Model

Description

The forward_backward function computes forward and backward probabilities of a hidden Markov model.

Usage

forward_backward(model, ...)
# S3 method for hmm
forward_backward(model, forward_only = FALSE, ...)
# S3 method for mhmm
forward_backward(model, forward_only = FALSE, ...)
# S3 method for nhmm
forward_backward(model, forward_only = FALSE, ...)
# S3 method for mnhmm
forward_backward(model, forward_only = FALSE, ...)

Value

A data.frame with log-values of forward and backward probabilities.

Arguments

model

A hidden Markov model.

...

Ignored.

forward_only

If TRUE, only forward probabilities are computed. The default is FALSE.

Examples

# Load a pre-defined MHMM
data("mhmm_biofam")

# Compute forward and backward probabilities
fb <- forward_backward(mhmm_biofam)

head(fb)
