FAQPage Schema
How do I detect anomalies in time series data without losing the original records?

To detect anomalies in time series data without losing records, you can use a Skill that flags deviations using Z-Score and differential mutation detection. It outputs annotated data instead of deleting rows, allowing full review of flagged financial or numeric datasets.

What is the best way to flag outliers in financial datasets for further review?

The best way to flag outliers in financial datasets is using Z-Score and differential mutation detection algorithms. This approach marks data points deviating from the norm while preserving the original data, enabling efficient identification of potential risks.

Can I use pandas to identify data anomalies in numeric datasets?

Yes, you can use pandas to identify data anomalies in numeric datasets. This Skill specifically requires pandas for data processing to compute Z-Scores and detect differential mutations, efficiently flagging anomalies in your time series data.

How does Z-Score and differential mutation detection work for time series anomaly detection?

Z-Score and differential mutation detection work for time series anomaly detection by identifying data points that deviate significantly from the statistical norm. This method flags sudden changes in numeric datasets, automating anomaly identification without data loss.

Do I need to clean my time series data before running anomaly detection?

You do not need to clean your time series data before running anomaly detection, as this Skill automates the inspection process. It flags potential anomalies in numeric datasets for review, actively increasing data quality by reducing manual inspection.

Are there limitations to using statistical analysis for finding anomalies in financial data?

A limitation of using statistical analysis like Z-Score for finding anomalies in financial data is that it identifies deviations from the norm without explaining the cause. It outputs flagging data for review, meaning manual investigation is still required to confirm risks.
