Description

Compute the theoretical autocorrelation function for an ARMA process.

Usage

ARMAacf_cpp(ar,ma,lag_max)

Arguments

ar

A vector of length p containing AR coefficients
ma

A vector of length q containing MA coefficients
lag_max

A unsigned integer indicating the maximum lag necessary

Details

This is an implementaiton of the ARMAacf function in R. It is approximately 40x times faster. The benchmark was done on iMac Late 2013 using vecLib as the BLAS.
