Confidences

• These are pdf's of -2lnQ for the 2 hypotheses in a test

• Confidences are integrals of the pdf's from the right

  • CLb: conf. in background
  • 1-CLb: test significance
  • CLsb: conf in sig.+bg.
  • CLs=CLsb/CLb: approximate conf. in sig.
  • These ensembles are no more invalid than those in FC!
