J. Bretagnolle et A. Klopotowski, ON THE EXISTENCE OF EXCHANGEABLE OR STATI ONARY-SEQUENCES OF S-BY-S INDEPENDENT RANDOM-VARIABLES, Annales de l'I.H.P. Probabilites et statistiques, 31(2), 1995, pp. 325-350
It is well known that infinite sequences of pairwise independent and e
xchangeable random variables do not exist, In this note we consider fi
nite sequences of random variables which are s by s independent and ex
changeable. We give examples of such sequences which cannot be extende
d above some dimension that can be explicitely computed. We have also
found some new examples of infinite painwise independent and stationna
ry sequences.
