Value at Risk, or VaR, is roughly speaking, a measure of how much money a bank or other financial firm can lose on its positions in a fixed period, such as 1 day, 10 days, or 1 year in a “worst case” (bottom 1 percent) scenario.

Without default risk, the price of this bond at date t is (6.3) P t ( F) = ∑ h = 1 ∞ F t + h B ( t, t + h). The bond price is derived by treating a fixed income bond as a portfolio of zero coupon bonds and by applying the arbitrage free condition. In the presence of default risk, the bond price will decrease.The Value at Risk (VaR) measures the risk affecting the market value V of a given position. Lh ≡ V0 – Vh is the loss between 0 and h, and FL its distribution function ( FL ( x) = Prob ( Lh ≤ x )). The VaR at the horizon h and with probability level p, VaR (h,p), is the p - quantile of Lh:4.5 Hypothesis Testing. In statistics, a hypothesis is a probabilistic assertion. A hypothesis might assert that a random variable’s mean is 1—or perhaps that its variance is less than 5. A hypothesis might state that a random variable is normally distributed. It might assert that two random variables are independent—or that they have the ...Example of Backtesting in Value at Risk.
