What problem does it solve?

This Skill provides a means to automatically convert a continuous variable into ordinal categories (quartiles, quintiles, deciles) without pre-specifying cutpoints, streamlining the categorization process for exploratory and statistical analyses.

Core Features & Use Cases

• Automatic Grouping: Automatically ranks continuous variables and groups them into equal frequency categories based on data distribution.
• No Pre-Specified Cutpoints: Removes the need for manual categorization and pre-definition of cutpoints.
• Use Case: When performing exploratory analyses, especially in epidemiology or socioeconomic research, this Skill helps to create groups such as income quintiles or biomarker values without predetermined thresholds.

Quick Start

Rank the variable 'income' into quintiles and output to a new dataset named 'income_quintiles'.
