LASSO Logistic Regression Analysis

When to Read External Files

Situation	File to Read	Purpose
Need algorithm details	`references/algorithm.md`	LASSO objective function, cross-validation, and interpretation
Need to run analysis	`scripts/main.R`	Execute: `Rscript scripts/main.R --input_file ... --group_file ...`
Encounter errors	`references/troubleshooting.md`	Common errors and solutions
Need CLI examples	`references/cli-guide.md`	Detailed CLI usage examples
Need test data	`tests/data/`	Sample input files for testing
Need workflow implementation details	`scripts/run_analysis.R`	Inspect orchestration, outputs, and file-writing behavior
Need input-validation or error-handling details	`scripts/utils.R`, `scripts/io.R`	Inspect validation, parsing, logging, and standardized safeguards
