Abstract: However, in the statement of Lemma 3 insufficient care was given to the support of the random variable I Y i with distribution HT ht appearing in (22) of [[2]]. It is known that HT X0<=3-cxXu ht , as stated in (34) of [[2]]. Let HT X0 ht and HT Xu ht be random variables with the extremal two-point cdf's HT F0 ht and HT Fu ht , respectively.
