Properties of GPD
Let f be a GPD density function with paramters { and 3 such that
-(--+1)
f(x) = B-1 (1+
where B > 0, x > 0 when & > 0 and 0 <x < -B/E when { < 0.
prove :
•(+ + 5x)) =
E ( In (1+
and
E (In (1+ x)) = ç*k!, ke N.
E ( In (1+
where E denotes the expectation operator over the distribution. And EX < o if and
only if { < 1.
