Pure White Noise
Computes ACF for a given series. Returns a vector of autocorrelations through lag p. Also produces bar graph of autocorrelations, with rejection region bands for testing (under white noise assumption) each autocorrelation = 0.Example: >> myacf = acf(y,12)Does not require any toolboxes.
