WebJan 1, 1977 · Abstract. It is well known that in the testing of a simple hypothesis H versus a simple alternative K, the sequential probability ratio test (SPRT) has the smallest average sample number (ASN) under H and K. Compared to the corresponding best fixed sample size (FSS) test, the saving in the average number of samples under H or K in the SPRT … WebWith the Clipped Surrogate Objective function, we have two probability ratios, one non-clipped and one clipped in a range (between [1 − ϵ, 1 + ϵ] [1 - \epsilon, 1 + \epsilon] [1 − …
