Abstract
We seek conditions for the exchangeable $\sigma$-field of an independent non-identically-distributed sequence of random variables to be trivial. A simple necessary condition is given, and this condition is shown to be sufficient when the range space is finite. In the case of a general range space, a stronger condition is shown to be sufficient.
