Statistical Validation & Testing

What problem does it solve?

This Skill addresses the critical need for ensuring the accuracy, reliability, and reproducibility of R-based statistical analyses, preventing errors and building confidence in results.

Core Features & Use Cases

• Unit Testing: Write and run tests for R functions using the testthat package.
• Output Validation: Verify model outputs, data transformations, and utility functions against known results or expected behavior.
• Edge Case Testing: Test code with boundary conditions, empty data, or missing values.
• Use Case: After developing a new R function for data cleaning, use this Skill to write testthat tests that confirm it correctly handles missing values, removes duplicates, and maintains expected column types.

Quick Start

Write a testthat test for the crossbasis function to ensure its dimensions are correct.
