element.indices: Get the score element indices

In cthmm: Latent Continuous Time Markov Chains

Description

The complete data score equations consist of elements such as nij-di*lambda ij, zi-pi, and o_ij-Ni*e_ij. Hence the score can be written as A-cB, where A is a vector of nij,zi,oij and B, di,1,Ni, and c, lambda ij,pi,eij

Usage

  element.indices(suff.stats, rate.matrix, emission.matrix,
    init.dist)

Arguments

suff.stats	table with coding all of the sufficient statistics
rate.matrix	the rate matrix
emission.matrix	the emission matrix
init.dist	vector with the initial distribution

Value

list with

l_a	row index of suff.stats corresponding to A
l_b	row index of suff.stats corresponding to B–for 1, this index is set to 0
c	vector of constants
