  Which of the following about the most common distribution used for peaks-over-threshold is false?
  I.       The distribution requires a threshold, shape, and scaling parameter.
  II.      The distribution of these extreme values follows the GEV distribution.
  III.    The distribution produces a curve that dips below the normal distribution prior to the tail and then moves above the normal distribution in a curved shape until it reached the extreme tail.
  IV.    The distribution provides a more accurate estimate of the event probabilities in the distribution tail, allowing VaR to be computed at high confidence levels.
  A.     I and II
  B.     II only
  C.     III and IV
  D.     IV only
  Answer: B
  GPD requires a threshold, shape, and scaling parameter. The distribution of these extreme values follows the GPD. GPD produces a curve that dips below the normal distribution prior to the tail and then moves above the normal distribution in a curved shape until it reaches the extreme tail. GPD provides a more accurate estimate of the event probabilities in the distribution tail, allowing VaR to be computed at high confidence levels.
