In the recent years, the copula models became a popular tool for modeling dependencies between random variables, especially in such fields as biostatistics, actuarial science, and finance.The copulas model has been extensively studied in a parametrical frame-work for the distribution function c. Large classes of copulas, such as the elliptic family, which contains the Gaussian copula and the Student copula, and the Archimedian family, which contains the Gumbel copula, the Clayton copula and the Frank copulas, have been identified.

The aim of this work is to establish an upper bound on L p$'$-losses (2 ‚ȧ p$'$ < 1) of the linear wavelet-based estimator for copula function when the copula function assumed to be bouned and the marginals are unknown and must be estimated from ranks.

Biography: I have finished my PhD in Statistics in Ferdowsi University of Mashad-Iran last year. I started working as an asistant professor in PNU university last year.

I have a particular interest in Nonparametric estimation, wavelets with applications in Biostatistics and Finance.
