This paper shows how p-values do not only create, as well known, wrong expectations in the case of flukes, but they might also dramatically diminish the `significance' of most likely genuine signals. As real life examples, the 2015 first detections of gravitational waves are discussed. The March 2016 statement of the American Statistical Association, warning scientists about interpretation and misuse of p-values, is also reminded and commented. (The paper is complemented with some remarks on…

On a curious bias arising when the $\sqrt{χ^2/ν}$ scaling prescription is first applied to a sub-sample of the individual results
As it is well known, the standard deviation of a weighted average depends only on the individual standard deviations, but not on the dispersion of the values around the mean. This property leads
Talking about Probability, Inference and Decisions. Part 1: The Witches of Bayes
In October 2017 the Italian National Institute of Statistics (ISTAT), Italy's body for official statistics, has published the book of fairy tales Le streghe di Bayes (The witches of Bayes) written by
Statistical analysis for explosives detection system test and evaluation
A method is described based on the probability confidence interval and expressed in terms of the upper confidence interval bound that reports the probability of successful detection and its level of statistical confidence, which provide useful measures of the system’s performance.
Probability, propensity and probability of propensities (and of probabilities)
The process of doing Science in condition of uncertainty is illustrated with a toy experiment in which the inferential and the forecasting aspects are both present. The fundamental aspects of
The Gauss' Bayes Factor
In 'Theoria motus corporum coelestium in sectionibus conicis solem ambientum' Gauss presents, as a theorem and with emphasis, the rule to update the ratio of probabilities of complementary


Bayesian model comparison applied to the Explorer–Nautilus 2001 coincidence data
Bayesian reasoning is applied to the data by the ROG Collaboration, in which gravitational wave (gw) signals are searched for in a coincidence experiment between Explorer and Nautilus. The use of
Probably a discovery: Bad mathematics means rough scientific communication
The main purpose of this note is to invite everybody, but especially journalists and general public, to mistrust claims not explicitly reported in terms of how much the authors should believe something, under well stated conditions and assumptions.
Constraints on the Higgs boson mass from direct searches and precision measurements
Abstract. We combine, within the framework of the standard model, the results of Higgs search experiments with the information coming from an accurate theoretical calculation and precision
The basic physics of the binary black hole merger GW150914
The first direct gravitational-wave detection was made by the Advanced Laser Interferometer Gravitational Wave Observatory on September 14, 2015. The GW150914 signal was strong enough to be apparent,
Bayes factor of the ATLAS diphoton excess: Using Bayes factors to understand anomalies at the LHC
Abstract.As an example of using Bayesian statistics in searches for new physics at the LHC, we present a calculation of Bayes factors for the erstwhile digamma resonance ($\digamma$Ϝ) versus the SM
Constraining the Higgs boson mass through the combination of direct search and precision measurement results
We show that the likelihood ratio of Higgs search experiments is a form to report the experimental results suitable to be combined with the information from precision measurements to obtain a joint
Bayesian coherent analysis of in-spiral gravitational wave signals with a detector network
The present operation of the ground-based network of gravitational-wave laser interferometers in enhanced configuration and the beginning of the construction of second-generation (or advanced)
Binary Black Hole Mergers in the First Advanced LIGO Observing Run
The first observational run of the Advanced LIGO detectors, from September 12, 2015 to January 19, 2016, saw the first detections of gravitational waves from binary black hole mergers. In this paper
Hint of lepton flavour non-universality in B meson decays
A bstractThe LHCb collaboration has recently presented their result on RK = ℬ(B+ → K+μ+μ−)/ ℬ(B+ → K+e+e−) for the dilepton invariant mass bin mℓℓ2 = 1 − 6 GeV2 (ℓ = μ, e). The measurement shows an
How Experiments End
"Galison provides excellent histories of three experimental episodes: the measurement of the gyromagnetic ratio of the electron, the discovery of the mu meson, or muon, and the discovery of weak
