Week 10 Limit setting Flashcards
what is construction of confidence belts based on
defining horizontal intervals according to a certain confidence level C
what is the coverage equation for confidence belts
P( μ ε[μ1, μ2] ) = C
what are 3 different types of coverage and their conditions
correct coverage when the coverage equation is satisfied
undercoverage when the coverage equation < C
overcoverage when the coverage equation > C
what causes the issue of flip-flopping
mix of vertical and horizontal construction of the confidence intervals
what is the Feldman&Cousins method
a limiting method that is strictly restricted to a horizontal construction that does not pre-define whether a central or upper interval is being created
what are the 2 caveats of the Feldman & Cousins method
In the case of 0 observed cases a measurement with greater levels of expected background can lead to a lower upper limit
It does not allow the inclusion of nuisance parameters which account for systematic uncertainties
