multipartiteBMFixedModel: Model selection and estimation of multipartite blockmodels

Description

Estimate the parameters and give the clustering for given numbers of blocks

Usage

multipartiteBMFixedModel(
  list_Net,
  v_distrib,
  namesFG,
  v_K,
  classifInit = NULL,
  nbCores = NULL,
  maxiterVE = NULL,
  maxiterVEM = NULL,
  verbose = TRUE
)

Value

Estimated parameters and a classification

Arguments

list_Net

A list of network (defined via the function DefineNetwork)

v_distrib

Type of proababilistic distributions in each network : if 0/1 then bernoulli, if counting then poisson, gaussian or Zero Inflated Gaussian (ZIgaussian) My default = Bernoulli. Must give a vector whose length is the number of networks in list_Net

namesFG

Names of functional groups (must correspond to names in listNet)

v_K

A vector with the numbers of blocks per functional group

classifInit

A list of initial classification for each functional group in the same order as in namesFG

nbCores

Number or cores used for the estimation. Not parallelized on windows. By default : half of the cores

maxiterVE

Maximum number of iterations in the VE step of the VEM algorithm. Default value = 1000

maxiterVEM

Maximum number of iterations of the VEM algorithm. Default value = 1000

verbose

Set to TRUE to display the current step of the search algorithm

Examples

namesFG <- c('A','B')
list_pi <- list(c(0.5,0.5),c(0.3,0.7)) # prop of blocks in each FG
E  <-  rbind(c(1,2),c(2,2)) # architecture of the multipartite net.
typeInter <- c( "inc","diradj")
v_distrib <- c('poisson','bernoulli')
list_theta <- list()
list_theta[[1]]   <- matrix(c(6.1, 8.9, 6.6, 3), 2, 2)
list_theta[[2]] <- matrix(c(0.7,1.0, 0.4, 0.6),2, 2)
list_Net <- rMBM(v_NQ = c(20,20),E , typeInter, v_distrib, list_pi,
                list_theta, namesFG = namesFG, seed = 2)$list_Net
