FAQ Frequently Asked Questions

What anomaly detection algorithms are available?
The tool offers three powerful algorithms: Z-score analysis for statistical outliers, Interquartile Range (IQR) method for robust detection, and Moving Average deviation for trend-based anomalies. Each algorithm can be fine-tuned with custom sensitivity thresholds.
How do I analyze my time series data for anomalies?
Upload your CSV data or paste values directly. The tool automatically detects timestamps and values, then applies your chosen algorithm. Results are displayed with interactive charts highlighting detected anomalies, complete with confidence scores and statistical summaries.
What data formats does the anomaly detector support?
The tool accepts CSV files, direct text input, and JSON format. It automatically handles various timestamp formats including ISO dates, Unix timestamps, and custom date patterns. Works perfectly on all devices and modern browsers.
How accurate is the anomaly detection for business applications?
The algorithms are industry-standard statistical methods used in production environments. Accuracy depends on data quality and chosen sensitivity settings. For critical business decisions, we recommend validating results with domain expertise and using multiple algorithms for confirmation.
Can I customize the sensitivity of anomaly detection?
Yes! Each algorithm offers adjustable sensitivity parameters. Z-score threshold (typically 2-3), IQR multiplier (1.5-3.0), and moving average window size can all be customized to match your specific use case and data characteristics.
