Probabilistic Anomaly Detection in Time Series Data

anomaly detection machine learning time series analysis
Prompt
Develop a sophisticated JavaScript algorithm for detecting statistical anomalies in time-series datasets using adaptive machine learning techniques. The solution should support multiple detection methods including Z-score, Interquartile Range (IQR), and ensemble probabilistic models. Create a configurable system that can automatically adjust sensitivity thresholds based on historical data patterns, with explicit support for handling seasonal variations and trend-based contextual anomalies.
