An Application Of Extreme Value Theory In Modelling Electricity Production In Kenya
(IISTE, 2014)Extreme Value Theory provides a well-established statistical model for the computation of extreme risk measure which includes, Value at Risk and Expected Shortfall. In this paper we apply Univariate Extreme Value Theory ... -
Application of extreme value theory in the estimation of value at risk in Kenyan stock market
(Int. J. Cur. Tr. Res, 2013)Most financial institutions have faced a lot of losses due to the fluctuations of commodities prices. Traditionally normal distribution was applied and could not capture rare events which caused enormous losses. The ... -
Application of Nonparametric Methods in Studying Energy Consumption
(University of Rwanda, 2011)Consumer behaviour towards different forms of energy varies over time. The variance can be so large that the quality of the estimation functional relationship between the response variable and its associated explanatory ... -
