SUMMARY. In this paper, we deal with sequences of exchangeable observations, which are conditionally independent and identically distributed with a common (random) distribution $\tau$, where $\tau$ is defined by the conditioning of a normalized random measure with independent increments. By application of a multidimensional version of the Faàa di Bruno formula, we derive explicit closed form expressions for the finite dimensional distributions and the predictive distributions of the sequence. The results are illustrated through suitable examples.
