Let X have a Pareto distribution with a: = 2 and () = 100. Determine the range of the mean excess loss function e(d) as d ranges over all positive numbers. Then let Y = l.lX. Determine the range of the ratio ey( d)/ ex( d) as d ranges over all positive numbers. Finally, let Z be X right censored at 500 (i.e., a limit of 500 is applied to X ). Determine the range of ez(d) as d ranges over the interval O to 500.
