Let X1, X2, ..., Xn be independent random variables having a common distribution in the domain of attraction of a stable law with exponent
< 2. Let {Xn1, Xn2, ..., Xnn} denote the sample {X1, X2, ..., Xn} arranged in order of decreasing magnitude:

It is known that the variables
and
, when suitably normalised, have a joint limiting distribution ((k)T, T(k)) as n
. We find the characteristic function of T(k) and show that for suitable constants ck, (k)Tck has a limiting stable distribution as k
. We derive a rate of convergence.
