- Course Overview
- Embark on an applied and immersive journey into “Time Series Analysis and Forecasting in Python,” mastering practical, industry-relevant techniques to predict future trends and patterns from historical data, blending theory with hands-on Python implementation.
- Learn to systematically decompose complex time series data into its fundamental componentsβtrend, seasonality, and irregular residualsβa crucial step for robust data preparation and effective model development.
- Progress logically from foundational univariate models to sophisticated multivariate approaches that expertly capture and analyze dynamic interdependencies among multiple related time series.
- Grasp essential time series concepts such as stationarity, understanding its critical role in model validity. Apply various statistical tests and transformations to optimize data for precise model building and reliable predictions.
- Requirements / Prerequisites
- A solid foundational understanding of Python programming, including basic syntax, data types, control structures, and function definitions, is crucial for comfortably engaging with all practical coding exercises.
- Familiarity with elementary statistical concepts, such as measures of central tendency, variability, and basic probability distributions, will significantly aid in grasping the underlying principles of time series models.
- An analytical mindset and eagerness to explore quantitative methodologies are key; no prior specific knowledge of time series analysis is assumed or required.
- Skills Covered / Tools Used
- Core Time Series Models (AR, MA, ARIMA): Master the construction and practical implementation of Autoregressive (AR), Moving Average (MA), ARMA, and advanced ARIMA models for understanding and forecasting diverse sequential data patterns.
- Seasonal & Exogenous Models (SARIMAX): Gain proficiency in building and interpreting Seasonal ARIMA with eXogenous regressors (SARIMAX) models, essential for effectively handling complex seasonality and integrating external influencing factors.
- Volatility & Multivariate Forecasting (GARCH, VAR): Implement Generalized Autoregressive Conditional Heteroskedasticity (GARCH) models for accurately predicting financial market volatility, and develop Vector Autoregression (VAR) models to analyze interdependencies across multiple time series.
- Automated Model Selection (Auto ARIMA): Utilize powerful automated tools, like Auto ARIMA, to efficiently identify and determine optimal ARIMA model parameters, significantly streamlining the iterative process of model identification and tuning.
- Comprehensive Model Validation & Metrics: Perform rigorous diagnostic checks on model residuals and apply a range of key performance metrics (e.g., RMSE, MAE, MAPE, SMAPE) to objectively assess model reliability, accuracy, and compare different forecasting approaches.
- Python Ecosystem for Time Series: Leverage industry-standard Python libraries including
statsmodelsfor core model implementation,pandasfor efficient data manipulation,numpyfor numerical computing, andmatplotlib/seabornfor comprehensive data visualization.
