    Hi Yes in 90% CL for 100 observations we have no of exceptions>10 to correctly reject the model ,if 5<no of exceptions<=10 we incorrectly accept the 95%Var model at 90%cl leading type II error and if 1<no of exceptions<=10 we incorrectly accept the 99% model at 90%cl ,from above its clear that...

    Practice question 3 - Backtesting VaR

    Hi Type I error is equal to significance level=1-CL. Our hypothesis test for model is:Ho:model is correct and Ha:model is incorrect 95% model has type I error probability as 5% is more probable to reject model(reject Ho) than 99%model whose type I error is 1% . It follows A and B and D re...

    Swap maximum potential exposure

    I dont know abt the Duration, The 1 day volatility is, σ(V) = [market_value * duration * yield volatility ] = 10,000,000 * 7.0 * 0.00074 Its just scaled by sqrt(10)=10^.5=3.16 to get volatility over 10 days as σ(V) = [market_value * duration * yield volatility *(10)^0.5] = 10,000,000 * 7.0 *...

    Standard Dev in Hypothesis Testing

    Hi For any sample default rate is X/n where X is no of defaults in a sample is binomial variable with std deviation sqrt(np(1-p)) ,p is popln/sample default rate. These sample default rates X/n will be according to CLT will be normally distributed with mean as popln default rate(E(X/n)=np/n=p)...

    Standard Dev in Hypothesis Testing

    Hi, The population std deviation is popln default rate*(1- popln default rate) here we are using tstatics and sample std deviation=sqrt(.15*(1-.15)) as proxy for popln std deviation. Also SE for sampling distbn=popln std deviation/sqrt(sample size)=sqrt(.15*.85)/sqrt(60) so tstat=sample default...

    VaR mapping commodity forwards

    Hi ES always calculates average of 5% of tail((1-CL)% in general) or avg of worst 5 losses for 95% CL. So ES of (99+98+97+96+95/5)97$ is valid. Var has 3 valid definitions as 5th worst loss/6thworst/avg of above 5th and 6th worst losses.(please refer to GARP 2015/2014 Sample papers to know...
