Simple Seasonality Test

Description

Checks for the presence of seasonality based on the QS test of Gomez and Maravall (1996).

Usage

seasonality_test(x, frequency = NULL)

Arguments

`x`	an (xts) vector (usually of a stationary series).
`frequency`	overrides any frequency automatically identified in the index of x.

Details

Given the identified frequency of the xts vector (using the sampling_frequency), the function checks for seasonality at that frequency. The frequency can be overridden by directly supplying a frequency argument, in which case y does not need to be a xts vector.
