A Note on Fisher Information and Imperfect Ranked-Set Sampling

Communications in Statistics - Theory and Methods, 2014, vol. 43, issue 13, 2726-2733

Abstract: We show by example that the Fisher information in an imperfect ranked-set sample may be higher than the Fisher information in a perfect ranked-set sample. This corrects certain misconceptions in the literature. The example also provides an additional counterexample to a common claim about the relationship between imperfect rankings and perfect rankings.
