General Aspects Regarding the Methodology for Prediction Risk
Journal Title: Revista Romana de Statistica - Year 2013, Vol 61, Issue 2
Abstract
In order to measure the total risk to which an investor or a financial institution is exposed when they invest in a financial asset, there needs to be a tool to capture this risk. The most widely used tool in measuring the total risk is Value at Risk. The first parameter that must be estimated is represented by the decay factor, because based on its value we will estimate further the volatility and Value at Risk. However, we are not just interested in computing the VaR for all considered models, but moreover we want to test if models used in these estimations are accurate and able to predict the risk. To achieve this objective we will use two types of test: unconditional coverage test and condiţional coverage test.
