R6 Class definition of a Multiplex SBM fit

Description

R6 Class definition of a Multiplex SBM fit

R6 Class definition of a Multiplex SBM fit

Details

This class is designed to give a representation and adjust a Multiplex SBM fitted with GREMLIN.

The list of parameters estimOptions essentially tunes the optimization process and the variational EM algorithm, with the following parameters

• "nbCores" integer for number of cores used. Default is 2

• "verbosity" integer for verbosity (0, 1). Default is 1

• "nbBlocksRange" List of length the number of functional groups, each element supplying the minimal and maximal number of blocks to be explored. The names of the list must be the names of the functional groups. Default value is from 1 to 10)

• "initBM" Boolean. True if using simple and bipartite SBM as initialisations. Default value = TRUE

• "maxiterVEM" Number of max. number of iterations in the VEM. Default value = 100

• "maxiterVE" Number of max. number of iterations in the VE. Default value = 100
