It is shown that the repeated significance test is a Bayes test for testing sequentially the sign of the drift of a Brownian motion. Its relation to Wald's sequential probability ratio test isâ€¦ (More)

The free-boundary and the martingale approach are competitive methods of solving discounted optimal stopping problems for one-dimensional time-homogeneous regular diffusion processes on infinite timeâ€¦ (More)

Let us consider the problem of sequential prediction of categorical data. Let D = {0, 1, . . . , dâˆ’1} denote the set of possible outcomes with d â‰¥ 2. Let x1, x2, . . . be an infinite sequence withâ€¦ (More)
