Penyesuaian distribusi proses keberangkatan sepeda motor dari lahan parkir saat waktu puncak

open access: yesMajalah Ilmiah Matematika dan Statistika, 2023
The study aims to model the distribution of motorcycle departures from the parking lot at peak times with the Poisson process approach. This process involves a discrete number of departures and continuous interdeparture time. The probability distribution

Median‐Based Unit Weibull (MBUW): A New Variants of Generalized Method of Moments and Percentile Estimators

open access: yesJournal of Probability and Statistics, Volume 2025, Issue 1, 2025.
This paper introduces a new two‐parameter unit Weibull distribution defined on the interval (0, 1). It discusses the methodology for deriving its probability density function (PDF), explores various properties, and presents related functions. Numerous figures illustrate the distribution and demonstrate its effectiveness in fitting a wide range of ...

Simulation algorithms for hierarchical Archimedean copulas beyond the completely monotone case

open access: yesDependence Modeling, 2019
Two simulation algorithms for hierarchical Archimedean copulas in the case when intra-group generators are not necessarily completely monotone are presented. Both generalize existing algorithms for the completely monotone case.

A new generalization of Lehmann type-II distribution: Theory, simulation, and applications to survival and failure rate data

open access: yesScientific African, 2021
In this paper, a potentiated lifetime model that demonstrates the bathtub-shaped hazard rate function is developed. This proposed model is referred to as Kumaraswamy modified size-biased Lehmann Type-II (Kum–MSBL–II) distribution.

Estimation and Prediction Under Different Schemes for a Flexible Symmetric Distribution With Applications

open access: yesJournal of Mathematics, Volume 2024, Issue 1, 2024.
This paper introduces a new probability distribution called the mixture symmetric gamma (MSG) distribution, which is defined as a mixture of two symmetric gamma distributions. Its statistical properties and applications are explored. We first examine its mathematical properties, including the possible shapes of the corresponding probability density ...

On Conditional Value at Risk (CoVaR) for tail-dependent copulas

open access: yesDependence Modeling, 2017
The paper deals with Conditional Value at Risk (CoVaR) for copulas with nontrivial tail dependence. We show that both in the standard and the modified settings, the tail dependence function determines the limiting properties of CoVaR as the conditioning ...

Dependent defaults and losses with factor copula models

open access: yesDependence Modeling, 2017
We present a class of flexible and tractable static factor models for the term structure of joint default probabilities, the factor copula models. These high-dimensional models remain parsimonious with paircopula constructions, and nest many standard ...

The functional average treatment effect

open access: yesJournal of Causal Inference
This article establishes the functional average as an important estimand for causal inference. The significance of the estimand lies in its robustness against traditional issues of confounding.
