How Is Time Series Forecasting Used For Outlier Detection? - The Friendly Statistician

How Is Time Series Forecasting Used For Outlier Detection? In this informative video, we’ll break down the fascinating world of time series forecasting and its role in identifying outliers within data sets. Understanding time series is essential, as it involves data points collected at regular intervals, which allows us to analyze trends over time. We’ll discuss various forecasting models, including Moving Averages and Autoregressive models, and how they help predict future values based on historical data.

Identifying outliers is a vital part of data analysis, and we’ll explain how model-based approaches can flag unusual data points that deviate from expected patterns. Additionally, we’ll cover statistical methods for setting thresholds to determine when a data point should be marked as an outlier. This practice is particularly useful in fields like finance and healthcare, where outliers can indicate errors or significant changes in data.

Once outliers are detected, we’ll explore options for addressing them, whether through removal or further analysis. We’ll also touch on the impact of outliers on forecasting accuracy and how addressing them can lead to more reliable predictions.
