  y,
  Adj,
  G,
  beta_grid = seq(0, 4, 0.2),
  PX = TRUE,
  maxIter_ICM = 10,
  maxIter = 50
)

Arguments

y

is n-by-d PCs.

G

is an integer specifying the numbers of clusters.

beta_grid

is a numeric vector specifying the smoothness parameter of Random Markov Field. The default is seq(0,4,0.2).

PX

is a logical value specifying the parameter expansion in EM algorithm.

maxIter_ICM

is the maximum iteration of ICM algorithm. The default is 10.

maxIter

is the maximum iteration of EM algorithm. The default is 50.

Adj_sp

is a sparse matrix of neighborhood.

Value

a list, We briefly explain the output of the SC.MEB.

The item 'x' storing clustering results.

The item 'gam' is the posterior probability matrix.

The item 'ell' is the opposite log-likelihood.

The item 'mu' is the mean of each component.

The item 'sigma' is the variance of each component.
