Density estimation deals with the problem of estimating probability density functions based on some data sampled from the PDF. It may use assumed forms of the distribution, parameterized in some way (parametric statistics), or it may avoid making assumptions about the form of the PDF (non-parametric statis-tics).

The objective of point estimation of parameters is to obtain a single number from the sample which will represent the unknown value of the parameter. Practically we did not know about the population mean and standard deviation i.e population parameters such as mean, standard deviation etc. Bayesian estimation of the parameters under SEL, LINEX, and Stein loss functions and 100(1 в€’ Оі)% HPD intervals are obtained. Also, the MLEs and asymptotic confidence intervals of the parameters are obtained.

estimation methods for copula parameters are usually motivated by density representations and decompositions for the log-likelihood of dependence mod- els as in (1) and (2). When the parameters appear linearly in these expressions then the least squares estimation problem can be solved in closed form, and it is relatively straightforward to derive the statistical properties for the resulting parameter estimates.
