# 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 |
