PROBABILISTIC FLOW MODEL OF FREIGHT ORDERING WITH CONSIDERATION OF REGULARITIES OF THEIR RECEPTION [PDF]

open access: yesAvtomobilʹnyj Transport (Harʹkov), 2014
An analytical model for calculating the probability of freightage obtaining by concrete carrier is proposed. The model takes into account the freightage waiting time, the parameters of a single freight flow and freight structure parameters.

Bias in random forest variable importance measures: Illustrations, sources and a solution

open access: yesBMC Bioinformatics, 2007
BackgroundVariable importance measures for random forests have been receiving increased attention as a means of variable selection in many classification tasks in bioinformatics and related scientific fields, for instance to select a subset of genetic ...

Addressing persistent challenges in digital image analysis of cancer tissue: resources developed from a hackathon

open access: yesMolecular Oncology, EarlyView.
Large multidimensional digital images of cancer tissue are becoming prolific, but many challenges exist to automatically extract relevant information from them using computational tools. We describe publicly available resources that have been developed jointly by expert and non‐expert computational biologists working together during a virtual hackathon

Characterizations of New Modified Weibull Distribution [PDF]

open access: yes, 2014
Several characterizations of a New Modified Weibull distribution, introduced by Doostmoradi et al. (2014), are presented. These characterizations are based on: (i) truncated moment of a function of the random variable; (ii) the hazard function; (iii) a ...

Invariance principle for variable speed random walks on trees

open access: yes, 2017
We consider stochastic processes on complete, locally compact tree-like metric spaces $(T,r)$ on their "natural scale" with boundedly finite speed measure $\nu$.

One-sample tests for a generalized Fréchet variance of a fuzzy random variable

open access: yes, 2010
A procedure to test hypotheses about the population variance of a fuzzy random variable is analyzed. The procedure is based on the theory of UH-statistics.

Explaining Fixed Effects: Random Effects Modeling of Time-Series Cross-Sectional and Panel Data*

open access: yesPolitical Science Research and Methods, 2014
This article challenges Fixed Effects (FE) modeling as the ‘default’ for time-series-cross-sectional and panel data. Understanding different within and between effects is crucial when choosing modeling strategies.

Cell‐free DNA aneuploidy score as a dynamic early response marker in prostate cancer

open access: yesMolecular Oncology, EarlyView.
mFast‐SeqS‐based genome‐wide aneuploidy scores are concordant with aneuploidy scores obtained by whole genome sequencing from tumor tissue and can predict response to ARSI treatment at baseline and, at an early time point, to ARSI and taxanes. This assay can be easily performed at low cost and requires little input of cfDNA. Cell‐free circulating tumor

A partial solution for lossless source coding with coded side information [PDF]

open access: yes, 2006
This paper considers the problem, first introduced by Ahlswede and Körner in 1975, of lossless source coding with coded side information. Specifically, let X and Y be two random variables such that X is desired losslessly at the decoder while Y serves as
