Título: "Exchangeability and the Cramér–Wold theorem."

Expositor: Ricardo  Ricardo FraimanFraiman (CMAT-Fcien) (UdelaR)

Resumen:
 
We address the problem of testing exchangeability and sign-invariant
exchangeability based on one-dimensional projections. For that purpose, we first
characterize those distributions that are (sign-invariant) exchangeable in terms
of their one-dimensional projections. Based on these results, we propose new
test procedures that are powerful, computationally efficient, and that
circumvent the curse of dimensionality. We compare our procedure with some
previous proposals in a small simulation study. Some of the results can be
extended to the case of infinite-dimensional spaces (multivariate functional
data). Joint work with Leonardo Moreno and Thomas Ransford.
