Systematic errors in the maximum-likelihood regression of Poisson count data: introducing the overdispersed χ2 distribution [PDF]
This paper presents a new method to estimate systematic errors in the maximum-likelihood regression of count data. The method is applicable in particular to X-ray spectra in situations where the Poisson log-likelihood, or the Cash goodness-of-fit ...

Nonparametric modeling of cosmological database on the χ2 distribution [PDF]
In the $\Lambda$CDM model, cosmological observations from the late and recent universe reveal a puzzling $\sim 4.5\sigma$ tension in the current rate of universe expansion.

A gap in the double white dwarf separation distribution caused by the common-envelope evolution: astrometric evidence from Gaia [PDF]
The trajectory of the center of light of an unresolved binary is different from that of its center of mass. Binary-induced stellar centroid wobbling can therefore be detected as an excess in the goodness-of-fit of the single-star astrometric model.

Superstatistical generalisations of Wishart-Laguerre ensembles of random matrices [PDF]
Using Beck and Cohen's superstatistics, we introduce in a systematic way a family of generalized Wishart–Laguerre ensembles of random matrices with Dyson index β = 1, 2 and 4. The entries of the data matrix are Gaussian random variables whose variances η

Confidence Interval Estimation for Intraclass Correlation Coefficient Under Unequal Family Sizes [PDF]
Confidence intervals (based on the χ2 -distribution and (Z) standard normal distribution) for the intraclass correlation coefficient under unequal family sizes based on a single multinormal sample have been proposed. It has been found that the confidence

CT location distribution of subarachnoid hemorrhage and its value in intracranial aneurysm detection
Objective To compare the CT location distribution of subarachnoid hemorrhage (SAH) caused by aneurysms at different locations, and to explore the value of CT hemorrhage distribution for improving the detection of aneurysms in CTA in diagnosing aneurysm ...
