Resumen de An urn model with non deterministic total replacement

T. Roldán

• A strong law is obtained for the process {Xn} that represents the proportion of balls of each colour in a generalized Pólya urn with non-deterministic total replacement. We prove that this process fits the Robbins-Monro scheme of stochastic approximation and, by means of the ODE method, we obtain its a.s. limit.
