Detailed Documentation

The ARMA (AutoRegressive Moving Average) model is a fundamental tool for time series analysis and forecasting. To better understand and apply ARMA models, we can implement them using MATLAB. In MATLAB, you can write code to implement ARMA models that performs time series data prediction. The implementation typically involves using built-in functions like arima() for model specification and estimate() for parameter estimation. Notably, when using ARMA models for forecasting, you can predict results for any number of steps ahead by utilizing the forecast() function, which makes ARMA models an indispensable tool in time series analysis. The code structure generally follows these steps: 1) Model identification and order selection, 2) Parameter estimation using maximum likelihood methods, and 3) Multi-step forecasting with prediction intervals.
