Variability Measures of Positive Random Variables

open access: yesPLoS ONE, 2011
During the stationary part of neuronal spiking response, the stimulus can be encoded in the firing rate, but also in the statistical structure of the interspike intervals. We propose and discuss two information-based measures of statistical dispersion of the interspike interval distribution, the entropy-based dispersion and Fisher information-based ...

Quantumness in Diagnostics of Marine Internal Combustion Engines and Other Ship Power Plant Machines

open access: yesPolish Maritime Research, 2023
The article provides proof that the diagnostics of marine internal combustion engines and other ship power plant machines should take into account the randomness and unpredictability of certain events, such as wear, damage, the variations of mechanical ...

An experimental study of the intrinsic stability of random forest variable importance measures

open access: yesBMC Bioinformatics, 2016
The stability of Variable Importance Measures (VIMs) based on random forest has recently received increased attention. Despite the extensive attention on traditional stability of data perturbations or parameter variations, few studies include influences ...

Significance improvement by randomized test in random sampling without replacement [PDF]

open access: yesarXiv, 2022
This paper studies one-sided hypothesis testing under random sampling without replacement. That is, when $n+1$ binary random variables $X_1,\ldots, X_{n+1}$ are subject to a permutation invariant distribution and $n$ binary random variables $X_1,\ldots, X_{n}$ are observed, we have proposed randomized tests with a randomization parameter for the upper ...

Variable importance-weighted random forests

open access: yesQuantitative Biology, 2017
BackgroundRandom Forests is a popular classification and regression method that has proven powerful for various prediction problems in biological studies. However, its performance often deteriorates when the number of features increases.

Estimation of the two-parameter Weibull distribution parameters using the coefficient of variation

open access: yesVojnotehnički Glasnik, 1996
This paper presents a method for estimating the reliability function parameters when reliability function is the 2-parametar Weibull regression. This model is often used in a reliability analysis in wide variety of situations to approximate successfully ...

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

open access: yesPopulation Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Characteristic value determination from small samples [PDF]

open access: yes, 2007
The paper deals with the characteristic value determination from relatively small samples. When the distribution and its parameters of a random variable are known, the characteristic value is deterministic quantity.

Еstimation of randomity of generators of keys of the crypto system

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
The aim of the study is to develop an algorithm for constructing an integer random variable representing random components of the keys of the RSA cryptosystem, and determining the table for the distribution of its probabilities.

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.
