Simultaneous Model Constructor

Description

Initialize model object required by the simultaneous methods.

Usage

simultaneous(
  seed = NULL,
  verbose = TRUE,
  init = "svd",
  n_max_iter = 10,
  n_loops = 10,
  tol = 1e-05,
  U_i_g = NULL,
  B_j_q = NULL,
  C_k_r = NULL
)

Arguments

seed	Seed for random sequence generation.
verbose	Flag to display output result for each loop.
init	The initialization method for the model parameters. Values could be 'svd','random','twcfta' or 'twfcta' Defaults to svd.
n_max_iter	Maximum number of iterations to optimize objective function.
n_loops	Number of runs/loops in search of the global result.
tol	Acceptable tolerance level.
U_i_g	Membership function matrix for the objects.
B_j_q	Component matrix for the variables.
C_k_r	Component matrix for the occasions.

Details

Two simultaneous models T3Clus and 3FKMeans are the implemented methods.

• T3Clus finds B_j_q and C_k_r such that the between-clusters deviance of the component scores is maximized.

• 3FKMeans finds B_j_q and C_k_r such that the within-clusters deviance of the component scores is minimized.

Value

An object of class "simultaneous".

Note

The model finds the best partition described by the best orthogonal linear combinations of the variables and orthogonal linear combinations of the occasions.
