  • Description: Skorohod discovered that if a sequence Q n {Q_n} of countably additive probabilities on a Polish space converges in the weak star topology, then, on a standard probability space, there are Q n {Q_n} -distributed f n {f_n} which converge almost surely. This note strengthens Skorohod’s result by associating, with each probability Q Q on a Polish space, a random variable f Q {f_Q} on a fixed standard probability space so that for each Q Q , (a) f Q {f_Q} has distribution Q Q and (b) with probability 1, f P {f_P} is continuous at P = Q P = Q .
