Statistical Anomalies

Detection

Statistical anomalies refer to data points or patterns that deviate significantly from the expected or normal behavior within a dataset. Their detection involves employing various quantitative techniques, such as outlier detection algorithms, deviation analysis, or machine learning models. Identifying these anomalies is crucial in financial markets as they can signal errors, fraud, market manipulation, or significant regime shifts. This process is fundamental for maintaining data integrity and market surveillance. It helps pinpoint unusual events.
