Mathematics, 2022 In this article, we introduce and study a new stochastic order of multivariate distributions, namely, the conditional likelihood ratio order. The proposed order and other stochastic orders are analyzed in the case of a bivariate exponential distributions

Stochastic Orderings of the Idle Time of Inactive Standby Systems
Mathematics, 2023 In this paper, we consider a failed cold standby system and obtain stochastic bounds on the idle time of such systems. We state and prove that if the last spare in the system is exponentially distributed and if the components have log-concave lifetime ...

Stochastic Comparisons of Lifetimes of Used Standby Systems
Mathematics, 2023 In this paper, we first establish upper stochastic bounds on the lifetime of a used cold standby system with arbitrary age, using the likelihood ratio order and the usual stochastic order.

Gaussian Mixture Models of Between-Source Variation for Likelihood Ratio Computation from Multivariate Data. [PDF]
PLoS ONE, 2016 In forensic science, trace evidence found at a crime scene and on suspect has to be evaluated from the measurements performed on them, usually in the form of multivariate data (for example, several chemical compound or physical characteristics). In order

Empirical likelihood inference for threshold autoregressive conditional heteroscedasticity model
Journal of Inequalities and Applications, 2021 This paper considers the parameter estimation problem of a first-order threshold autoregressive conditional heteroscedasticity model by using the empirical likelihood method.

Discrete Likelihood Ratio Order for Power Series Distribution
Revista Colombiana de Estadística, 2014 It is well-known that some discrete distributions belong to the power series distribution (PSD) family, so it seems useful to study conditions to establish the discrete likelihood ratio order for this family.

Testing for Trends in Excesses Over a Threshold Using the Generalized Pareto Distribution
Revstat Statistical Journal, 2020 The Generalized Pareto Distribution (GPD) is used for modeling exceedances over thresholds. The general form of the GPD depends on three parameters: the location parameter µ; the scale parameter (β > 0); and the shape parameter (−∞ < ξ < ∞).

Agency Contracts under Maximum-Entropy
Entropy, 2021 This article proposes the application of the maximum-entropy principle (MEP) to agency contracting (where a principal hires an agent to make decisions on their behalf) in situations where the principal and agent only have partial knowledge on the ...

Properties of N-Laplace Transform Ratio Order and L(N)-Class of Life Distributions
Revstat Statistical Journal, 2016 One notion of stochastic comparisons of non-negative random variables based on ratios of nth derivative of Laplace transforms (n-Laplace transform order or shortly ≤n-Lt-r order) is introduced by Mulero et al. (2010).
