چکیده
In this study, the accuracy of copula-based model in simulation dew point temperature various climates Iran was investigated, using simulations based on vine copulas such as C-, D-, and R-vine copulas. By examining their tree sequences, best copula sequence AIC, BIC, log-likelihood were selected. The results show that complete similarity our case between D- copulas, selected C-vine fit well dependence minimum maximum air temperatures temperature. analyzed root mean square error (RMSE), Nash-Sutcliffe efficiency (NSE) coefficient, violin plots. has high at all stations. min (max) RMSE is related to Kerman (Ahvaz) station with = 0.396 oC (0.617 oC). Also, NSE Ahvaz (Urmia) 0.925 (0.955). according plot, it possible appreciate acceptable certainty model. Due diversity sequences use rotated states internal possibility interfering effective parameters dimensions, are reliable have no restrictions. This can be used estimate due full coverage range changes data.

Selection of Vine Copulas
Vine copula models have proven themselves as a very flexible class of multivariate copula models with regard to symmetry and tail dependence for pairs of variables. The full specification of a vine model requires the choice of vine tree structure, copula families for each pair copula term and their corresponding parameters. In this survey we discuss the different approaches, both frequentist as...
متن کاملTruncation of vine copulas using fit indices
Vine copulas are flexible multivariate dependence models, which are built up from a set of bivariate copulas in different hierarchical levels. However, vine copulas have a computational complexity that is increasing quadratically in the number of variables. This complexity can be reduced by focusing on the sub-class of truncated vine copulas, which use only a limited number of hierarchical leve...
متن کاملBayesian Model Selection of Regular Vine Copulas
Regular vine copulas are a novel and very flexible class of dependence models. This paper presents a reversible jump MCMC strategy for Bayesian model selection and inference of regular vine copulas, which can select all levels of a regular vine copula simultaneously. This is a substantial improvement over existing frequentist and Bayesian strategies, which can only select in a sequential, level...

متن کاملTail dependence functions and vine copulas
Tail dependence and conditional tail dependence functions describe, respectively, the tail probabilities and conditional tail probabilities of a copula at various relative scales. The properties as well as the interplay of these two functions are established based upon their homogeneous structures. The extremal dependence of a copula, as described by its extreme value copulas, is shown to be co...
