Sufficient Conditions for Some Stochastic Orders of Discrete Random Variables with Applications in Reliability
F. Belzunce, C. MartÃnez-Riquelme, M. Pereda
In this paper we focus on providing sufficient conditions for some well-known stochastic orders in reliability but dealing with the discrete versions of them, filling a gap in the…
Comparisons of policies based on relevation and replacement by a new one unit in reliability
Belzunce, F., MartÃnez-Riquelme +5
The purpose of this paper is to study the role of the relevation transform, where a failed unit is replaced by a used unit with the same age as the failed one, as an alternative to…
A new stochastic dominance criterion for dependent random variables with applications
F. Belzunce, C. MartÃnez-Riquelme
In this paper we develop a new tool for the comparison of paired data based on a new criterion of stochastic dominance that takes into account the dependence structure of the rando…
Sufficient conditions for some transform orders based on the quantile density ratio
A. Arriaza, F. Belzunce, C. MartÃnez-Riquelme
In this paper we focus on providing sufficient conditions for some transform orders for which the quantile densities ratio is non-monotone and, therefore, the convex transform orde…
Assessing dominance in survival functions: A test for right-censored data
Félix Belzunce, Carolina MartÃnez-Riquelme, Jaime Valenciano
This paper proposes a new statistical test to assess the dominance of survival functions in the presence of right-censored data. Traditional methods, such as the log-rank test, are…
New stochastic comparisons based on tail values at risk
Félix Belzunce, Alba M. Franco-Pereira, Julio Mulero
In this paper we provide a new criterion for the comparison of claims, when we have conditional claims arising in stop loss contracts or contracts with franchise deductible. These…
