Abstract:
Discrete distributions on exchangeable \{ 0,1 \}-valued
trials are studied based on de Finetti's theorem.
By using an extension of de Finetti's theorem,
discrete distributions on exchangeable multistate trials
are also investigated. As an application of partial exchangeable
sequences, discrete distributions on a Markov exchangeable
sequence are also studied. Further, as a new type of partial
exchangeable sequence, a binary sequence model is proposed
which has partial exchangeability of order $k$. The sequence
is a mixture of binary sequences of order $k$ if it is recurrent.
