Quantile Regression in Space-Time Varying Coefficient Model of Upper Respiratory Tract Infections Data

open access: yesMathematics, 2023
Space-time varying coefficient models, which are used to identify the effects of covariates that change over time and spatial location, have been widely studied in recent years. One such model, called the quantile regression model, is particularly useful

Stochastic Generator of a New Family of Lifetime Distributions with Illustration

open access: yesRevstat Statistical Journal
In this article, a new family of lifetime distributions is introduced to help researchers model different types of data sets. Furthermore, the maximum likelihood method was used in estimating the model's parameters.

A Software Reliability Model Using Quantile Function

open access: yesJournal of Probability and Statistics, 2014
We study a class of software reliability models using quantile function. Various distributional properties of the class of distributions are studied. We also discuss the reliability characteristics of the class of distributions.

Quantile regression for mixed models with an application to examine blood pressure trends in China [PDF]

open access: yes, 2015
Cardiometabolic diseases have substantially increased in China in the past 20 years and blood pressure is a primary modifiable risk factor. Using data from the China Health and Nutrition Survey, we examine blood pressure trends in China from 1991 to 2009,

On function-on-function linear quantile regression

open access: yesJournal of Applied Statistics
We present two innovative functional partial quantile regression algorithms designed to accurately and efficiently estimate the regression coefficient function within the function-on-function linear quantile regression model. Our algorithms utilize functional partial quantile regression decomposition to effectively project the infinite-dimensional ...

Multivariate quantile inactivity time with medical applications

open access: yesAIP Advances
The concept of α-quantile inactivity time was developed for situations with bivariate or multivariate random lifetimes. In this situation, each element has a specific history related to itself, indicating that the corresponding event occurred earlier ...

A new class of gamma distribution

open access: yesActa Scientiarum: Technology, 2017
This paper presents a new class of probability distributions generated from the gamma distribution. For the new class proposed, we present several statistical properties, such as the risk function, expansions to density and cumulative function, moment ...
