Title: Discovery of statistical equivalence classes using computer algebra
Authors: Eva Riccomagno - Università degli Studi di Genova (Italy) [presenting]
Abstract: Representations of certain polynomials in terms of a nested representation are intrinsically linked to labelled event trees. A recursive formula corresponds to a construction of such polynomials from a tree and gives an algorithm on the computer algebra software CoCoA to derive all staged trees from a polynomial. We use the results in applications linked to staged tree models.
