viterbi: Viterbi algorithm

In lamortenera/kfoots: Model multivariate count data with a mixture model

Description

Standard viterbi algorithm in the log space

Usage

viterbi(initP, trans, lliks, seqlens)

Arguments

initP	matrix of initial probabilities: each column corresponds to a sequence
trans	transition matrix (rows are previous state, columns are next state)
lliks	matrix with emission probabilities for each datapoint and each state. Columns are datapoints and rows are states.
seqlens	length of each subsequence of datapoints (set this to ncol(lliks) if there is only one sequence).

Value

a list with the following arguments:

vpath	viterbi path
vllik	log-likelihood of the viterbi path
