Introduction Suppose X1 X2 . are independent and identically distributed iid random variables with common distribution function df F. Let Mn max X1 . Xn denote the maximum of the first n random variables and let w F sup x F x 1 denote the upper end point of F. The extreme value theory seeks norming constants an 0 bn e and a nondegenerate df G such that the df of a normalized version of Mn converges to G that is x Pr iMn - an bn Fn anX bn G x as n - 00. If this holds for suitable choices of an and bn then it is said that G is an extreme value df and F is in the domain of attraction of G written as F e D G . For suitable constants a 0 and b e R one can write G ax b Gy x exp ị - 1 yx 1 q for all 1 yx 0 and y e . For y 0 is equivalent to m U x where U t 1 1 - F t inf t e R 1 1 - F x t that is U t is a regularly varying function at infinity with index y.

Its practical applications have been wide-ranging fire protection and insurance problems model for the extremely high temperatures prediction of the high return levels of wind speeds relevant for the design of civil engineering structures model for the extreme occurrences in
