Historical Simulation, Value-at-Risk, and expected shortfall - Backtesting

6 important questions on Historical Simulation, Value-at-Risk, and expected shortfall - Backtesting

What is unconditional coverage

If losses only exceed VaR approoximately 100*p% of the time

If thing are unconditiona coverage and indepedence its called

Conditiona coverage

What is the biggest problem of this graph

The clustering of VaR, they use HS and that has this short commings
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

Discribe the standard test for checking if the amount of sequances is different from p of Var.

What is the procedure of the uncondition coverage test

If we test a value larger than 2.7055 we reject the null for 10% significance.  The p value is 1-fx1 = p value so if the value is lower than the p value we reject the null if its higher we can't reject the null and have to accept it.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
