Abstract
Reynolds has proposed a sequential procedure for testing the hypothesis that the distribution of a sequence of i.i.d. random variables is symmetric about zero. The critical region and expected sample size of the test are approximated by using the fact that the test statistic behaves asymptotically like a Brownian motion process. In this paper we propose to use approximations based on a continuous non-homogeneous Markov chain. Monte Carlo studies show this approach to be much more accurate in determining appropriate critical regions and in finding expected sample size.
