Description

Tuning Parameters for ARIMA Models

Usage

non_seasonal_ar(range = c(0L, 5L), trans = NULL)

non_seasonal_differences(range = c(0L, 2L), trans = NULL)

non_seasonal_ma(range = c(0L, 5L), trans = NULL)

seasonal_ar(range = c(0L, 2L), trans = NULL)

seasonal_differences(range = c(0L, 1L), trans = NULL)

seasonal_ma(range = c(0L, 2L), trans = NULL)

Arguments

range

A two-element vector holding the defaults for the smallest and largest possible values, respectively. If a transformation is specified, these values should be in the transformed units.

trans

A trans object from the scales package, such as scales::transform_log10() or scales::transform_reciprocal(). If not provided, the default is used which matches the units used in range. If no transformation, NULL.
