Asymptotic distribution of the likelihood ratio test statistic with inequality-constrained nuisance parameters
Clara Bertinelli Salucci
The asymptotic distribution of the likelihood-ratio statistic for testing parameters on the boundary is well known to be a chi-squared mixture. The mixture weights have been shown…

The asymptotic distribution of the likelihood ratio test statistic in two-peak discovery experiments
Clara Bertinelli Salucci, Hedvig Borgen Reiersrud, A. L. Read +2
Likelihood ratio tests are widely used in high-energy physics, where the test statistic is usually assumed to follow a chi-squared distribution with a number of degrees of freedom…

A note on the asymptotic distribution of the Likelihood Ratio Test statistic under boundary conditions
Clara Bertinelli Salucci, Anders Kvellestad, Riccardo De Bin
In the context of likelihood ratio testing with parameters on the boundary, we revisit two situations for which there are some discrepancies in the literature: the case of two para…
