ARIMA: Time series prediction models

Description

Constructors for the modeling class representing a time series modeling and prediction method based on a particular model.

Usage

ARIMA(train_par = list(), pred_par = list(level = c(80, 95)))
ETS(train_par = list(), pred_par = list(level = c(80, 95)))
HW(train_par = list(), pred_par = list(level = c(80, 95)))
TF(train_par = list(), pred_par = list(level = c(80, 95)))
NNET(
  size = 5,
  train_par = NULL,
  pred_par = list(level = c(80, 95)),
  sw = SW(window_len = size + 1),
  proc = list(MM = MinMax())
)
RFrst(
  ntree = 500,
  train_par = NULL,
  pred_par = list(level = c(80, 95)),
