Programs Descriptions

1. lepvec_Pt.py -Cut base analysis.
2. chisquare.py -Script that test gives all permutations of b tag jets for chisquare.
3. MVA.py -Script that uses a MutiVariate Algorithm (MVA)/Boosted Decision Tree(BDT).
4. RocCurve.py -Script that recreates ROC curve plots from the BDT.
5. add_SF_branches.py

   • SF Branch: The script calculates and adds SF branches to your ROOT files. These SF branches contain correction factors used to mitigate systematic errors and enhance the precision of data analysis.

   • Efficient Processing: The script efficiently iterates through each event in the ROOT file, calculates SF values, and updates the corresponding branches. It also tracks the processing time and displays progress, ensuring a smooth augmentation process.

Programs Parser Variables/ Outputs

• lepvec_Pt.py

  --x=i where i = 1-4: ttHH,ttbb,ttH,ttZ.

  --help brings up help.

• chisquare.py

  N/A

• MVA.py

  --branch=i where i = phase1-4

  Output file is `ROC_data_file.csv'.
