Description

The function returns the parameters of an automatically fitted ARIMA model, including non-seasonal and seasonal orders and drift.

Usage

1
arimapar(timeseries, na.action=stats::na.omit, xreg=NULL)

Arguments

timeseries

A vector or univariate time series which contains the values used for fitting an ARIMA model.

na.action

A function for treating missing values in timeseries. The default function is na.omit, which omits any missing values found in timeseries.

xreg

A vector, matrix, data frame or times series of external regressors used for fitting the ARIMA model. It must have the same number of rows as timeseries. Ignored if NULL.

Details

The ARIMA model whose adjusted parameters are presented is automatically fitted by the auto.arima function in the forecast package. In order to avoid drift errors, the function introduces an auxiliary regressor whose values are a sequence of consecutive integer numbers starting from 1. For more details, see the auto.arima function in the forecast package.

Value

A numeric vector giving the number of AR, MA, seasonal AR and seasonal MA coefficients, plus the period and the number of non-seasonal and seasonal differences of the automatically fitted ARIMA model. It is also presented the value of the fitted drift constant.
