Time Series Forecasting
What is it
Time series forecasting specifically applies statistical and machine learning models to predict future values of data collected over time, building on time series analysis (trend, seasonality) to generate genuine forecasts with quantified uncertainty.
Why it matters
Forecasting is one of the most directly commercially valuable applications of statistics — inventory planning, staffing, financial markets, and energy demand all depend on genuinely reliable time-based forecasts to make costly decisions in advance.
Exam tip
Always report a forecast with a prediction interval, not just a single number — a forecast without a sense of its own uncertainty gives false confidence, and the width of that interval is often more informative to decision-makers than the central forecast itself.
