Autoregressive models are used to investigate stationary and nonstationary wind data collected in the field. Nonparametric techniques are currently used to classify the records as stationary or nonstationary. The autoregressive models for the stationary and nonstationary records are compared using a Kruskal-Wallis test and conclusions are drawn. An alternative method for defining stationarity based on the autoregressive model is proposed.
