Initialization options with S3 classes

init.options(
  init.method = "hc",
  hc.options = list(modelName = "VVV", use = "SVD"),
  exp.init = list(mahala = TRUE),
  mix.method = "Gower kmeans",
  user.class = integer()
)

Arguments

init.method: Name of method used to set initial values. If init.method = 'user', must define 'user.class' with a classification vector.
hc.options: Model names and use when init.method is 'hc' following conventions of mclust::mclust.options()
exp.init: Turn on mahala initialization when expert network
mix.method: Initialization methods when data are mixed. Default method when data are Tweedie distributed.
user.class: Vector of classification vector set by user and required when init.method = 'user'

Value

list of initialization specifications
