Time Series Forecasting for Managers – All forecasts are wrong but some are useful


Time series forecasting is a crucial aspect of business decision-making, widely used in finance, supply chain management, and production planning. Despite its importance, it remains an under-appreciated technique in data science education, often overshadowed by more popular machine learning methods. This talk aims to address this gap by providing an overview of time series forecasting techniques and their applications in various business contexts.

The talk will cover the Forecaster's Toolbox, including benchmark/simple forecasting methods, techniques for simplifying the forecasting task, and methods for residual analysis to check if the forecasting method has utilized all available information. Participants will learn to use a range of forecasting methods, including ETS, ARIMA, SARIMA, VAR models, and machine learning models such as XGBoost, Random Forest, and SVR.

The talk is intended for graduate students, professionals, and MBA students seeking an introduction to forecasting methods without diving too deep into theoretical details. Participants will develop skills, mindsets, and behaviors sought after in the industry today.

Background Knowledge:

For the talk we require zero familiarity but for a hands on session basic knowledge of python and statistics is required.
