SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automates comprehensive outlier detection and data quality assessment, applying IQR-based thresholds and combining skewness and kurtosis analyses to guide preprocessing for non-normal data.

Core Features & Use Cases

  • IQR-based detection across numeric columns to identify anomalous values.
  • Distribution characterization via skewness and kurtosis to inform cleaning decisions.
  • Summary reporting and visualization support for downstream data pipelines.

Quick Start

Run outlier detection on your dataset to identify extreme values and assess distribution shape, then summarize findings in a report.

FAQPage Schema
How do I detect outliers in non-normal tabular data?

Outlier detection in non-normal tabular data applies IQR-based thresholds across numeric columns to identify anomalous values, while computing skewness and kurtosis to characterize distribution shape and guide preprocessing decisions.

What's the best way to assess data quality for skewed datasets?

Assessing data quality for skewed datasets involves computing skewness and kurtosis metrics alongside IQR-based outlier detection, which together quantify distribution shape and extreme values to inform automated cleaning workflows.

Can I use pandas for automated outlier detection and preprocessing?

Yes, automated outlier detection and preprocessing applies IQR-based thresholds across pandas numeric columns, outputting a structured summary and visualization-ready data for downstream ML pipelines.

How does IQR-based detection work for extreme values?

IQR-based detection calculates interquartile range thresholds to flag extreme values in numeric columns, providing a robust method for non-normal distributions where standard deviation approaches fail.

Does outlier detection work with non-normal distributions?

Yes, outlier detection for non-normal distributions uses IQR-based thresholds and skewness-kurtosis analysis, avoiding normality assumptions to effectively characterize and clean tabular numeric data across domains.
