Summary Sequential sampling A simple survey of Walds theory of sequential sampling is given, followed by a modification of the rejection and acceptation lines. The rejection and acceptation lines of the Waldtest are lines of a constant ratio between the likelihoods of two hypotheses. The modified rejection and acceptation lines are curves, giving a constant ratio between the likelihood of one hypothesis and the maximum likelihood. The modified lines closely fit those of Wald, but ensure a natural end to the sampling before a given sample number is reached. A simple manner to evaluate rejection and acceptation probabilities of a hypothesis is still lacking, the computation now being quite inconvenient.
