Time Series ARIMA Models
Time series ARIMA models are applied with time series data of variables measured over time. Time series analysis examines relationships of variables over time such as commodity prices or crop yields. Time series models may be used for analyzing the effects of a specific event (such as the effects of the recession on unemployment rates) or for forecasting (for example to predict economic growth or future prices).
