DcLbmPath-class {greed}

Degree corrected Latent Block Model hierarchical fit results class

Description

An S4 class to represent a fit of a degree corrected stochastic block model for co_clustering, extend IclPath-class.

Slots

model

a DcLbm-class object to store the model fitted

name

generative model name

icl

icl value of the fitted model

K

number of extracted clusters over row and columns

Krow

number of extracted row clusters

Kcol

number of extracted column clusters

cl

a numeric vector with row and columns cluster indexes

obs_stats

a list with the following elements:

• counts: numeric vector of size K with number of elements in each clusters

• din: numeric vector of size K which store the sums of in-degrees for each clusters

• dout: numeric vector of size K which store the sums of out-degrees for each clusters

• x_counts: matrix of size K*K with the number of links between each pair of clusters

• co_x_counts: matrix of size Krow*Kcol with the number of links between each pair of row and column cluster

clrow

a numeric vector with row cluster indexes

clcol

a numeric vector with column cluster indexes

Nrow

number of rows

Ncol

number of columns

path

a list of size K-1 with each part of the path described by:

• icl1: icl value reach with this solution for alpha=1

• logalpha: log(alpha) value were this solution is better than its parent

• K: number of clusters

• cl: vector of cluster indexes

• k,l: index of the cluster that were merged at this step

• merge_mat: lower triangular matrix of delta icl values

• obs_stats: a list with the elements:

  • counts: numeric vector of size K with number of elements in each clusters

  • din: numeric vector of size K which store the sums of in-degrees for each clusters

  • dout: numeric vector of size K which store the sums of out-degrees for each clusters

  • x_counts: matrix of size K*K with the number of links between each pair of clusters

  • co_x_counts: matrix of size Krow*Kcol with the number of links between each pair of row and column cluster
