Prediction function for hmm

Description

Predicts the underlying state sequence for an observed sequence newdata given a hmm model

Usage

## S3 method for class 'hmm'
predict(object, newdata,method = "viterbi", ...)

Arguments

object	An object of class hmm
newdata	A vector or list of observations
method	Prediction method (see details)
...	further arguments passed to or from other methods.

Details

If method="viterbi", this technique applies the Viterbi algorithm for HMMs, producing the most likely sequence of states given the observed data. If method="smoothed", then the individually most likely (or smoothed) state sequence is produced, along with a matrix with the respective probabilities for each state.

Value

Returns a hsmm.data object, suitable for plotting.

newdata	A vector or list of observations
s	A vector containing the reconstructed state sequence
N	The lengths of each sequence
p	A matrix where the rows represent time steps and the columns are the probability for the respective state (only produced when method="smoothed")
