On the relation between Hodges‐Lehmann efficiency and Pitman efficiency

Canadian Journal of Statistics, 1989
AbstractThe relation between Hodges–Lehmann efficiency and Pitman efficiency is studied in the context of testing one‐sided hypotheses about a real‐valued parameter. It is first shown that for tests based on sums of independently and identically distributed observations local Hodges‐Lehmann efficiency is equivalent to Pitman efficiency.

Detection diversity of spatio-temporal data using Pitman's efficiency for low SNR regimes

2016 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2016
In this work, we use Pitman's efficiency to characterize the diversity of a spatio-temporal distributed detection system. Pitman's efficiency directly measures the detection ability of the data at low signal to noise ratios (SNRs). We study how the statistics of spatio-temporal distributed data affect the diversity of the system.

A lower bound for the pitman efficiency of Friedman type tests

Statistics & Probability Letters, 1983
Abstract An expression for the sharp lower bound for the efficiency of any Friedman type test with respect to the Friedman type test with optimal scores under weak model restrictions is given and calculated explicitely for the classical Friedman test.

Relations between Pitman efficiency and Fisher information

1970
Some fundamental relations between the efficacy of a test statistic for any finite sample and information in that statistic are derived. These results are used to point out the relations between Pitman efficiency and Fisher information. The equivalence of Pitaman efficiency and Fisher's definition of asymptotic relative efficiency for estimates is ...

The Combination of the Sign and Wilcoxon Tests for Symmetry and Their Pitman Efficiency

2001
We consider the efficiency properties of the test of symmetry based on the sequence of statistics Gn = aS n +bW n , where S n and W n are the classical sign and Wilcoxon statistics and a and b are some constants. Pitman efficiency of this test with respect to the student test in the case of location alternatives and its maximum with respect to a and b ...
