Summary

• The likelihood ratio is a common element in the analysis of search results (essentially required).

• The differences between FC and this analysis start out small but hypothesis testing and interval setting are different.

  • LR(FC) =
  • LR(search)=

• A search must include an attempt to falsify the new physics hypothesis.

  • The value of any confidence or credibility interval in the absence of a significant signal is questionnable at best.
  • I recommend to not report CI until it says something about a signal.
