About

This Python program contains a simple analysis and comparison of multiple statistical weighting methods, including inPlot/sPlot¹ and Q-Factors². It is intended to show the need for a correction in the Q-Factors method, which occasionally fails because it does not use the proper event weighting scheme.

Usage

1. Clone the repository: git clone [email protected]:denehoffman/qfactors_splot.git
2. Install the required libraries: pip install -r requirements.txt
3. Run the analysis script: python analysis.py
4. Profit?

SLURM Usage

1. Modify 'run_analysis.sh'
2. Execute the SLURM submission script: ./submit_jobs.sh

Disclaimer

This analysis is part of an ongoing project which will eventually be published, please don't scoop me, I'll know it and raise hell :)
