Although this approach sufficed as a test of general relativity, physicists have wanted to see all the terms changing together, and Haster’s method using pi offers a way of doing just that.

Let S0 be any sequential probability ratio test for deciding between two simple alternatives H0 and H1, and S1 another test for the same purpose. We define (i, j = 0, 1): αi (Sj) = probability, under ...

An approximate pivot is constructed for the problem of estimating a normal mean θ following a truncated sequential probability ratio test and shown to provide a useful method for constructing ...
