Theorem 3.3 (SR procedure, cf. [ 22 ]). Let ( x [1],…, x [ ν ], x [ ν +1],…) be a sequence of observed data where the x [ i ] are independent random variables with density for i ≤ ν and density f 0 for i > ν where the change-point ν is a deterministic unknown value.
WebLorden’s essential supremum metric, whereas the Shiryaev-Roberts procedure is optimal for detecting a change that occurs at a distant time horizon. At the same time, a randomized extension of the Shiryaev-Roberts test proposed by Pollak, enjoys a very strong asymptotic minimax property with respect to Pollak’s supremum metric. Web5. Comparison with the Shiryaev–Roberts change point detection scheme. An alternative approach common in the change-point literature is the Shiryaev–Roberts (SR) change point detection scheme [19, 20] which, according to Vexler and Hutson , can also be considered as Bayes factor type test.

These two methods combine conditional likelihood ratios in other ways. A comparison is also made with the Shewhart method that is a commonly used method.
