Comparison of nonparametric estimates of the survival functions

Вестник Самарского университета: Естественнонаучная серия, 2023
The article compares three types of estimates: exponential, multiplying and power structures for the survival function of three random censoring observations on the right. It was previously established that all these three estimates are equivalent with a

Application of survival function in robust scheduling of production jobs

Conference on Computer Science and Information Systems, 2017
Scheduling production jobs in the real production system requires considering a number of factors which may prove to exert a negative effect on the production processes.

A New Lifetime Distribution with Decreasing and Upside-Down Bathtub-Shaped Hazard Rate Function

Statistica, 2020
We introduce a new lifetime distribution, called the alpha-power transformed Lomax (APTL) distribution which generalizes the Lomax distribution to provide better fits than the Lomax distribution and some of its known generalizations.

Analysis of p53 transactivation domain mutants reveals Acad11 as a metabolic target important for p53 pro-survival function.

Cell Reports, 2015
The p53 tumor suppressor plays a key role in maintaining cellular integrity. In response to diverse stress signals, p53 can trigger apoptosis to eliminate damaged cells or cell-cycle arrest to enable cells to cope with stress and survive.

Waiting times between orders and trades in double-auction markets [PDF]

, 2006
In this paper, the survival function of waiting times between orders and the corresponding trades in a double-auction market is studied both by means of experiments and of empirical data.

CD36-mediated metabolic adaptation supports regulatory T cell survival and function in tumors

Nature Immunology, 2019
Depleting regulatory T cells (T reg cells) to counteract immunosuppressive features of the tumor microenvironment (TME) is an attractive strategy for cancer treatment; however, autoimmunity due to systemic impairment of their suppressive function limits ...

Estimating Propensity Scores and Causal Survival Functions Using Prevalent Survival Data [PDF]

Biometrics, 2012
SummaryThis article develops semiparametric approaches for estimation of propensity scores and causal survival functions from prevalent survival data. The analytical problem arises when the prevalent sampling is adopted for collecting failure times and, as a result, the covariates are incompletely observed due to their association with failure time ...

Aging functions and multivariate notions of NBU and IFR [PDF]

, 2010
For d≥2, let X=(X1, …, Xd) be a vector of exchangeable continuous lifetimes with joint survival function $\overline{F}$. For such models, we study some properties of multivariate aging of $\overline{F}$ that are described by means of the multivariate ...

The rich get richer and the poor get poorer - the Matthew mechanism as an approach to explain selection effects and the occurrence of multiple medalists in the "production" of international success in alpine ski racing

Current Issues in Sport Science, 2018
The study addresses two questions that are under debate in the literature and exemplifies their examination in alpine ski racing. Firstly, are successful athletes the product of a long-term continuous intervention and/or socialization process or do they ...
