Free Metaplectic K-Wigner Distribution: Uncertainty Principles and Applications
This study focuses on a novel parameterized Wigner distribution, which is an organic integration of the free metaplectic Wigner distribution and the K-Wigner distribution.

Generalized distributions of order k associated with success runs in Bernoulli trials
In a sequence of independent Bernoulli trials, by counting multidimensional lattice paths in order to compute the probability of a first-passage event, we derive and study a generalized negative binomial distribution of order k, type I, which extends to ...

Inference Based on k-Record Values from Generalized Exponential Distribution
In this paper, the lower k-record values arising from a two parameter generalized exponential distribution is considered. The maximum likelihood estimators for the shape parameter and scale parameter are obtained.

Impact of Metastatic Patterns on Survival and Response to Therapy in Neuroblastoma
ABSTRACT Background While the presence of metastases in neuroblastoma (NB) is a well‐established prognostic factor, the clinical significance of dissemination patterns and tumour burden and their impact on response and survival remains poorly understood.

Bias of group generators in finite and profinite groups: known results and open problems [PDF]
We analyze some properties of the distribution Q G,k of the first component in a k -tuple chosen uniformly in the set of all the k -tuples generating a finite group G (the limiting distribution of the product replacement algorithm). In particular,

On the conditional distribution of a multivariate Normal given a transformation – the linear case
We show that the orthogonal projection operator onto the range of the adjoint T⁎ of a linear operator T can be represented as UT, where U is an invertible linear operator. Given a Normal random vector Y and a linear operator T, we use this representation

ABSTRACT Background Germ cell tumors (GCTs) often arise in the ovaries and testes (extracranial) but can also develop in the brain (intracranial). We examined the relationship of individual, family, and community‐level socioeconomic status (SES) with stage of disease at diagnosis in a cohort of pediatric patients with GCT from Children's Oncology Group

Ultrasonic Echosignal Applied to Human Skin Lesions Characterization
The paper presents a classification of the healthy skin and the skin lesions (basal cell carcinoma) basing on a statistics of the envelope of ultrasonic echoes. The echoes envelopes distributions were modeled using Rayleigh and K-distribution.

La loi de Pascal restreinte et ses cas particuliers; Constrained Pascal distribution and its special cases [PDF]
Pascal distribution, Pa(r, /pi), also called Negative binomial distribution, pertains to the trial number n at which the first r successes have been obtained, each trial being the realization of a Bernoulli variable with success probability /pi.
