What are Yule-Walker equations used for?

The autoregressive model parameters are obtained from the autocovariance of the time series by solving a system of linear equations. The Yule-Walker equations provide a straightforward means to estimate an autoregressive model from data.

What is Yule Walker estimation?

The Yule-Walker Method block estimates the power spectral density (PSD) of the input using the Yule-Walker AR method. This method, also called the autocorrelation method, fits an autoregressive (AR) model to the windowed input data. It does so by minimizing the forward prediction error in the least squares sense.
