Note: The implementation of SLIDE is provided by the R function slide in the abess package on CRAN.

• 🖥️ Bash script (batch.sh): Automates execution of all numerical simulation studies.
• 📊 R scripts (.R): Implement baseline methods, evaluation metrics, simulation studies, and real-data analysis of the congressional voting dataset.
• 📁 Data files (.csv): Used for real-world data analysis. Available on
  👉 Dropbox.

• simu_degree.R — empirical sample complexity analysis w.r.t. degree.
• simu_beta.R — empirical sample complexity analysis w.r.t. maximum signal.
• simu_high.R — experiments for high-dimensional cases.
• simu_p.R — empirical sample complexity analysis w.r.t. dimension.
• simu_ws.R — empirical sample complexity analysis w.r.t. weakest signal.
• DataAnalysis.R — real-data analysis, including data cleaning, estimation of graphical structure among senators, and visualization.

• simulation_main.R — executes a method on a simulated dataset.
• method_implementation.R — implementations of baseline methods (RPLE, RISE, logRISE, ELASSO, RLRF).
• evaluation.R — evaluation metrics (e.g., Frobenius norm, true positive rate).

Each script corresponds to figures/tables in the paper:

1. 📈 Reproduce real-data results (Figure 4):
