lb_calculation: Calculate the lower bound

In cobiclust: Biclustering via Latent Block Model Adapted to Overdispersed Count Data

Description

Calculate the lower bound

Usage

lb_calculation(x = x, qu_param = qu_param, s_ik = s_ik, pi_c = pi_c,
  t_jg = t_jg, rho_c = rho_c, mu_i = mu_i, nu_j = nu_j,
  alpha_c = alpha_c, a = a, akg = TRUE)

Arguments

x	a matrix of observations. Columns correspond to biological samples and rows to microorganisms.
s_ik	s_ik.
pi_c	pi_c.
t_jg	t_jg.
rho_c	rho_c.
mu_i	mu_i.
nu_j	nu_j.
alpha_c	a matrix the terms of interactions.
a	a.
akg	a logical variable indicating whether to use a common dispersion parameter (akg = FALSE) or a dispersion parameter per cocluster (akg = TRUE).
qu.param	qu.param.

Value

a list of 2 elements.

lb

value of the lower bound.

ent

value of the entropy term.
