Does anyone have any reference for a sequential estimator for proportions?
I am planning an experiment to measure the probability of a certain event happening and would like to know how many observations to take to estimate it to within a certain accuracy. Clearly, this will depend of the size of the probability we end up observing about which our option will change sequentially as we obtain more information.
Classical Wald sequential ratio tests can be very efficient for two groups. Is there a parallel for the one sample case.
