Anomaly Detection Package

Introduction

This package provides a simple anomaly detection algorithm for identifying anomalies in time series data using z-score thresholding.

Installation

To install the package, use npm:

npm install anomaly-detection

Usage

const detectAnomalies = require('anomaly-detection');

// Example time series data
const data = [10, 12, 8, 14, 11, 20, 7, 9, 13, 15, 16];
// Set z-score threshold
const threshold = 2.5;

// Detect anomalies
const anomalies = detectAnomalies(data, threshold);
console.log('Anomalies detected at indices:', anomalies);

Functionality

The detectAnomalies function takes two parameters:

• data: An array representing time series data.
• threshold: A z-score threshold for anomaly detection.

It returns an array containing the indices of anomalies detected in the provided time series data.
