yulewalker Fit an AR (p)-model with Yule-Walker estimates given a vector C of autocovariances '[gamma_0, ..., gamma_p]'. Calling Sequence A = yulewalker(C) [A,V]= yulewalker(C) Parameters C: Autocovariances Description Fit an AR (p)-model with Yule-Walker estimates given a vector C of autocovariances '[gamma_0, ..., gamma_p]'. Returns the AR coefficients, A, and the variance of white noise, V.
