repr_exp: Exponential smoothing seasonal coefficients as representation

In PetoLau/TSrepr: Time Series Representations

Description

The repr_exp computes exponential smoothing seasonal coefficients.

Usage

repr_exp(x, freq, alpha = TRUE, gamma = TRUE)

Arguments

x	the numeric vector (time series)
freq	the frequency of the time series
alpha	the smoothing factor (default is TRUE - automatic determination of smoothing factor), or number between 0 to 1
gamma	the seasonal smoothing factor (default is TRUE - automatic determination of seasonal smoothing factor), or number between 0 to 1

Details

This function extracts exponential smoothing seasonal coefficients and uses them as time series representation. You can set smoothing factors (alpha, gamma) manually, but recommended is automatic method (set to TRUE). The trend component is not included in computations.

Value

the numeric vector of seasonal coefficients
