Phase 11 · Time Series Analysis
TopicsARIMA Models
Part of the Data Science Roadmap.
Summary
A classical forecasting model combining AutoRegression (past values), Integration (differencing), and Moving Average (past errors) — a strong, interpretable baseline for many time series problems.
How to Learn This
- 1Fit a basic ARIMA model on a sample time series using a library like statsmodels.
- 2Learn what the (p, d, q) parameters each control conceptually.
- 3Use ACF/PACF plots to get intuition for choosing reasonable starting parameter values.
