Computing Sum of the Sample Autocorrelation Function

Description

The sum of the sample autocorrelation function, found in many standard time series textbooks and software, at lag h is considered. It is shown that this sum is always minus half for any stationary time series with arbitrary length L.

Usage

SACF(x)

Arguments
