A Method for Solving Reliability of Route Travel Time

Journal of Function Spaces, 2020
In order to obtain an effective method for solving route travel time reliability, this paper proposes an effective new method to calculate travel time reliability using an independent link travel time function. Based on several months of historical data,

Goodness-of-fit testing for regime-switching models [PDF]

In this paper we propose a novel goodness-of-fit testing scheme for regime-switching models. We consider models with an observable, as well as, a latent state process.

Multi-objective interval prediction of wind power based on conditional copula function

Journal of Modern Power Systems and Clean Energy, 2019
Interval prediction of wind power, which features the upper and lower limits of wind power at a given confidence level, plays a significant role in accurate prediction and stability of the power grid integrated with wind power.

A Kiefer--Wolfowitz theorem for convex densities

, 2007
Kiefer and Wolfowitz [Z. Wahrsch. Verw. Gebiete 34 (1976) 73--85] showed that if $F$ is a strictly curved concave distribution function (corresponding to a strictly monotone density $f$), then the Maximum Likelihood Estimator $\hat{F}_n$, which is, in ...

An Analysis of Relationship among Income Inequality, Poverty, and Income Mobility, Based on Distribution Functions

Abstract and Applied Analysis, 2014
Many studies show that the relationship among income inequality, poverty, and income mobility needs to be further discussed. Meanwhile, some researches on Distribution Function offer new perspective and methods to analyze this issue.

Renewed empirical formulas for estimating Weibull distribution parameters

Компьютерная оптика
The empirical formulas proposed in the literature for estimating the parameters of a two-parameter Weibull distribution, obtained using the equations of the moment method, are considered. It is noted that the formulas used to estimate the shape parameter

Classification of images using Gaussian copula model in empirical cumulative distribution function space.

PLoS ONE
This study introduces an innovative approach to image classification that uses Gaussian copulas with an Empirical Cumulative Distribution Function (ECDF) approach. The strategic use of distribution functions as feature descriptors simplifies the approach

Risk Efficiencies of Empirical Bayes and Generalized Maximum Likelihood Estimates for Rayleigh Model under Censored Data

Journal of Probability and Statistics, 2014
The comparison of empirical Bayes and generalized maximum likelihood estimates of reliability performances is made in terms of risk efficiencies when the data are progressively Type II censored from Rayleigh distribution.
