De finetti's representation theorem
Websions of de Finetti’s classical theorem and its finite version along different directions; see, e.g., [11] and the references therein. The classical de Finetti representation theorem has been shown to hold for exchangeable processes with values in much more general spaces than {0,1} [15], and for mixtures of Markov chains [12]. Webmeasures for which de Finetti's characterization fails. Fig. 3. de Finetti's theorem yields a unique mixture of i.i.d. measures in the case of an infinite sequence. A glance at Figure 3 …
