When fitting a distribution in excess of a threshold as part of the body-tail distribution method described by the equation below, how is the parameter 'p' calculated.
Here, F(x) is the severity distribution. F(Tail) and F(Body) are the parametric distributions selected for the tail and the body, and T is the threshold in excess of which the tail is considered to begin.

Which of the following statements are correct:
I. A training set is a set of data used to create a model, while a control set is a set of data is used to prove that the model actually works II. Cleansing, aggregating or ensuring data integrity is a task for the IT department, and is not a risk manager's responsibility III. Lack of information on the quality of underlying securities and assets was a major cause of the collapse in the CDO markets during the credit crisis that started in 2007 IV. The problem of lack of historical data can be addressed reasonably satisfactorily by using analytical approaches

Which of the following is true in relation to the application of Extreme Value Theory when applied to operational risk measurement?
I. EVT focuses on extreme losses that are generally not covered by standard distribution assumptions II. EVT considers the distribution of losses in the tails III. The Peaks-over-thresholds (POT) and the generalized Pareto distributions are used to model extreme value distributions IV. EVT is concerned with average losses beyond a given level of confidence
