Simulation of potential evapotranspiration values based on vine copula

open access: yesMeteorological Applications, 2021
Vine copula had a great impact on the study and analysis of dependence structures in various sciences. In multivariate analyses with dimensions of more than two variables, it is associated with computational complexities that solve vine copulas and these

Indirect test of M-S circuits using multiple specification band guarding [PDF]

open access: yes, 2016
Testing analog and mixed-signal circuits is a costly task due to the required test time targets and high end technical resources. Indirect testing methods partially address these issues providing an efficient solution using easy to measure CUT ...

Is CT-based perfusion and collateral imaging sensitive to time since stroke onset?

open access: yesFrontiers in Neurology, 2015
PurposeCT-based perfusion and collateral imaging is increasingly used in the assessment of patients with acute stroke. Time of stroke onset is a critical factor in determining eligibility for and benefit from thrombolysis. Animal studies predict that the

Distortion risk measures for sums of dependent losses [PDF]

open access: yes, 2010
We discuss two distinct approaches, for distorting risk measures of sums of dependent random variables, which preserve the property of coherence. The first, based on distorted expectations, operates on the survival function of the sum.

Construction of asymmetric copulas and its application in two-dimensional reliability modelling [PDF]

open access: yes, 2014
Copulas offer a useful tool in modelling the dependence among random variables. In the literature, most of the existing copulas are symmetric while data collected from the real world may exhibit asymmetric nature.

Application of vine copulas to dependence analysis of water quality data [PDF]

open access: yesJournal of Applied Research in Water and Wastewater, 2022
In this study, using vine copulas and tree sequences, dependence analysis of groundwater quality variables (Total hardness (TH), Sodium adsorption ratio (SAR), Sodium percentage (Na %) and magnesium (Mg)) was performed.
