Understand
We describe likelihood-based statistical tests for use in high energy physics for the discovery of new phenomena and for construction of confidence intervals on model parameters.
- We focus on the properties of the test procedures that allow one to account for systematic uncertainties.
- Explicit formulae for the asymptotic distributions of test statistics are derived using results of Wilks and Wald.
- We motivate and justify the use of a representative data set, called the "Asimov data set", which provides a simple method to obtain the median experimental sensitivity of a search or measurement as well as fluctuations about this expectation.
