In funcharts: Functional Control Charts

Performs the estimation of gaussian mixtures of regression models and gaussian mixture models. Used in FMRCC_PhaseI.

Description

Performs the estimation of gaussian mixtures of regression models and gaussian mixture models. Used in FMRCC_PhaseI.

Usage

mixregfit_multivariate(
  y,
  x,
  k,
  init_met = "random",
  intercept = FALSE,
  eps = 1e-06,
  max_iter = 500,
  model_Sigma
)

Arguments

y	a matrix with the scores of the response variable
x	a matrix with the scores of the covariates
k	the number of groups to consider in the model estimation
init_met	the method to initialize the model, it can be 'kmeans' or 'random'. Default is 'kmeans'
intercept	logical, if TRUE the model includes an intercept. Default is TRUE
eps	the convergence criterion. Default is 1e-6
max_iter	the maximum number of iterations. Default is 500
model_Sigma	the parametrization of the covariance. It can be 'VVV', 'EEE', 'VII' or 'EII', with no default

Value

a list with the estimated parameters of the model
