Convergence in Distribution of the P–P Process in L1[0,1]$$ {\boldsymbol{L}}^{\mathbf{1}}\left[\mathbf{0},\mathbf{1}\right] $$

open access: yesStat, Volume 15, Issue 4, December 2026.
ABSTRACT We show that the percentile–percentile (P–P) process constructed from an independent and identically distributed sample of pairs converges in distribution in L1[0,1]$$ {L}^1\left[0,1\right] $$ if and only if the associated P–P curve is absolutely continuous.

Copula bivariate probit models: with an application to medical expenditures [PDF]

open access: yes
The bivariate probit model is frequently used for estimating the effect of an endogenous binary regressor (the "treatment") on a binary health outcome variable.

Inference Procedures for Copula-Based Models of Bivariate Dependence [PDF]

open access: yes, 2021
In this thesis, we develop inference procedures for copula-based models of bivariate dependence. We first investigate the distribution of Kendall’s functions for joint survivors since Kendall’s functions are important for identifying Archimedean copula ...

A Copula-Based Scenario Generation Method for Renewable Wind Power Outputs of Two Wind Farms

open access: yesEnergies
Renewable wind power output is characterized by strong randomness, volatility, and spatial dependence, which makes accurate two-adjacent wind farm scenario generation essential for stochastic dispatch and secure operation of power systems.

Compound Meteorological and Hydrological Hot‐Dry and Hot‐Wet Extremes Over Global Land Areas: Spatiotemporal Changes, Attribution, and Drivers

open access: yesInternational Journal of Climatology, Volume 46, Issue 14, 30 November 2026.
The changes in joint return period of compound meteorological hot‐dry (CMHHE) and hot‐wet (CMHWE) and compound hydrological hot‐dry (CHHDE) and hot‐wet (CHHWE) extremes were attributed to changes in associated univariate extremes and their dependence.

Pricing bivariate option under GARCH processes with time-varying copula [PDF]

open access: yes
This paper develops a method for pricing bivariate contingent claims under General Autoregressive Conditionally Heteroskedastic (GARCH) process. As the association between the underlying assets may vary over time, the dynamic copula with time-varying ...

GENERATION OF WEIBULL BIVARIATE DEPENDENT FAILURE TIMES USING COPULAS GENERACIÓN DE TIEMPOS DE FALLA DEPENDIENTES WEIBULL BIVARIADOS USANDO CÓPULAS

open access: yesRevista Colombiana de Estadística, 2008
The bivariate Weibull distribution is very important in both reliability and survival analysis. The dependence for these kind of problems has been gaining great importance in recent years.

Exploring Two Modified Ali-Mikhail-Haq Copulas and New Bivariate Logistic Distributions

open access: yesPan-American Journal of Mathematics
The Ali-Mikhail-Haq copula is a bivariate ratio-type Archimedean copula known for its simplicity and flexibility in modeling moderate negative and positive dependence structures, making it widely used in various fields.

Complex Versus Parsimonious Site‐Based Stochastic Ground Motion Models: Which One Is Better?

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 14, Page 3714-3731, November 2026.
ABSTRACT Stochastic ground motion models (GMMs) provide a probabilistic representation of seismic input and are increasingly important for uncertainty quantification (UQ) in earthquake engineering. This study focuses on site‐based stochastic GMMs, which learn the statistical features of selected datasets of seismic records and generate statistically ...

Testing the bivariate distribution of daily equity returns using copulas. An application to the Spanish stock market [PDF]

open access: yes
In this paper we deal with the identification of dependencies between time series of equity returns. Marginal distribution functions are assumed to be known, and a bivariate chi-square test of fit is applied in a fully parametric copula approach. Several
