Sensitivity optimization of multichannel searches for new signals
Giovanni Punzi
The frequentist definition of sensitivity of a search for new phenomena proposed in arXiv:0308063 has been utilized in a number of published experimental searches. In most cases, t…
A Statistical Prescription to Estimate Properly Normalized Distributions of Different Particle Species
Massimo Casarsa, Pierluigi Catastini, Giovanni Punzi +1
We describe a statistical method to avoid biased estimation of the content of different particle species. We consider the case when the particle identification information strongly…
Notes on statistical separation of classes of events
Giovanni Punzi
This short note contains some definitions and formulas about the power of an observable in statistically separating different classes of events.
Bias-Free Estimation in Multicomponent Maximum Likelihood Fits with Component-Dependent Templates
P. Catastini, G. Punzi
The possibility of strong biases in a multicomponent Maximum Likelihood fits with component-dependent templates has been demonstrated in some toy problems. We discuss here in detai…
Ordering Algorithms and Confidence Intervals in the Presence of Nuisance Parameters
Giovanni Punzi
We discuss some issues arising in the evaluation of confidence intervals in the presence of nuisance parameters (systematic uncertainties) by means of direct Neyman construction in…
Comments on Likelihood fits with variable resolution
Giovanni Punzi
Unbinned likelihood fits are frequent in Physics, and often involve complex functions with several components. We discuss the potential pitfalls of situations where the templates u…
