Statistical Problems in Particle Physics, Astrophysics and Cosmology
This article reviews aspects of significance testing. Problems of detection of a specific signal with background noise from observed Poisson counts of events is used as a basic example throughout. In particular we discuss issues of using alternative test-statistics, unbinned likelihood fits, and comparing unweighted and weighted histograms. We point at the possibility of adding simultaneous confidence intervals to the statistical toolbox normally used by particle physicists.doi:10.1142/9781860948985_0006 fatcat:eu3sv3txtzdyjp4qglrxugpeoa
