That is, any number of exceptions from 0 to xtechniues the cumulative probability up to x. Other MathWorks country sites are not optimized for visits from your location. Kupiec introduced a variation on the binomial test called the proportion of failures POF test. CiteULike is a free online bibliography manager.
The POF test statistic is. For more information, see References for Jorion and bin. It is unlikely that too many exceptions come from a correct VaR model.

There are no reviews of this article. The TUFF test looks at when the first rejection occurred. You may hide this message.
This is machine translation Translated by. All Examples Functions Apps. Market risk is the risk of losses in positions arising from movements in market prices.
This is the p -value for the observed number of exceptions x. The corresponding VaR limits are also given in monetary units. In addition, it uses a likelihood technlques to test whether the probability of exceptions is synchronized with the probability p implied by the VaR confidence level.
The corresponding VaR limits are also given as a proportion or percentage. Januarypp.

Verlfying can use this daily data to assess the performance of VaR models, which is the goal of VaR backtesting. The automated translation of this page is provided by a general purpose third party translator tool. Find this article at Save current location: By computing the probability of observing x exceptions, you can compute the probability of wrongly rejecting a good model when x exceptions occur.
