| Abstract: | Abstract In this paper the theory of fixed sample nonparametric m-interval partition detectors is extended to include sequential operation. A formulation for sequential m-interval partition detector is given which requires knowledge of only (m ? 1) quantiles under a Lehmann alternative and, in addition, the slope of the distribution at these quantiles under a shift of the mean alternative. A theorem is proven that permits the use of Fisher's information as a bound on performance and assures the existence of a locally most powerful sequential partition detector. In addition, a reduced partition space concept is introduced to combat impulsive noise interference. |
