چکیده

In this paper we analyse nonparametric methods to estimate risk measures in loss distributions. We study kernel estimation for Value-at-Risk and Tail Value-at-Risk based on transformation of the original data. The proposed method consists of a double transformation kernel estimation. We show that a suitable bandwidth selection criterion has a direct expression for the optimal smoothing parameter. The bandwidth can accommodate to the given extreme quantile level and expected shortfall. The procedure is useful for large data sets frequently available in finance and insurance.

Value at Risk Estimation using the Kappa Distribution with Application to Insurance Data

The heavy tailed distributions have mostly been used for modeling the financial data. The kappa distribution has higher peak and heavier tail than the normal distribution. In this paper, we consider the estimation of the three unknown parameters of a Kappa distribution for evaluating the value at risk measure. The value at risk (VaR) as a quantile of a distribution is one of the import...

A method to estimate an extreme quantile that requires no distributional assumptions is presented. The approach is based on transformed kernel estimation of the cumulative distribution function (cdf). The proposed method consists of a double transformation kernel estimation. We derive optimal bandwidth selection methods that have a direct expression for the smoothing parameter. The bandwidth ca...

Developing Non-linear Dynamic Model to Estimate Value at Risk, Considering the Effects of Asymmetric News: Evidence from Tehran Stock Exchange

Empirical studies show that there is stronger dependency between large losses than large profit in financial market, which undermine the performance of using symmetric distribution for modeling these asymmetric. That is why the assuming normal joint distribution of returns is not suitable because of considering the linier dependence, and can be lead to inappropriate estimate of VaR. Copula theo...
