Department of Mathematics National University of Singapore Academic year (2000/2001) I Summary Value at Risk (VaR) is one of the most popular tools used to estimate exposure to market risks, and it measures the worst expected loss at a given confidence level. In this report, we explain the concept of VaR, and then describe in detail some methods of VaR computation. We then discuss some VaR tools that are particularly useful for risk management, including marginal VaR, incremental VaR and component

ECONOMETRICS INTRODUCTION We will examine the data set of wealth, age, family size and income. In this data, our dependent variable is wealth and independent variables are age, family size and income. We will estimate and interpret how independent variables affect the dependent variable. We will use that equation: WEALTH = c1+ c2INCOME + c3AGE + c4FSIZE + u DATA AND METHODOLOGY The data of wealth is unstructured or undated and it include 9275 observations
