update_Q_col_block: Block update the Q matrix by column

In zhenkewu/rewind: Reconstructing Etiology with Binary Decomposition

Description

This function updates Q matrix by Gibbs sampler (without identifiability constraints)

Usage

update_Q_col_block(Y, Q_old, H, z, t, mylist, p, theta, psi)

Arguments

Y	binary data matrix
Q_old	the Q matrix from the last scan in Gibbs sampler (of dimension M by L)
H	matrix of latent state profiles, rows for N subjects, columns for M latent states
z	a vector of individual cluster indicators
t	the number of clusters at an iteration
mylist	the ordered list that keeps the cluster ids in increasing order
p	latent state prevalences; a vector of length identical to the columns of H.
theta, psi	True and false positive rates, each of length L

Value

A Q matrix with all elements updated.
