The authors present an improved ranked set two-sample Mann-Whitney-Wilcoxon test for a location shift between samples from two distributions F and G. They define a function that measures the amount of information provided by each observation from the two samples, given the actual joint ranking of all the units in a set. This information function is used as a guide for improving the Pitman effic...

Nonparametric or distribution-free charts can be useful in statistical process control when there is limited knowledge about the underlying process. In this paper a Shewhart-type chart is considered for the location, based on the Mann-Whitney statistic. The control limit calculations use Lugannani-Rice saddlepoint, Edgeworth and other approximation methods along with Monte Carlo estimation and ...

In CBIR system, relevance feedback is used to improve the retrieval performance. In this paper, a new MannWhitney test based method is presented to identify the features which can distinguish relevant and irrelevant images in a retrieved set. Then the discriminating features are given more emphasis to improve retrieval performance. Proposed scheme is implemented for two different similarity mea...

PURPOSE To determine whether pupil enlargement during phacotrabeculectomy affects postoperative visual acuity and intraocular pressure (IOP) compared to combined surgery without pupil enlargement. METHODS A retrospective study of 74 patients who underwent combined phacotrabeculectomy with (37 eyes) or without (37 eyes) pupil enlargement was performed. Postoperative outcome measures included b...

INTRODUCTION The aim of the present study was to investigate and compare the apical sealing ability of Resilon/Epiphany-filled root canals with those that were obturated with gutta-percha/AH-Plus endodontic sealer. MATERIALS AND METHODS A total of 60 extracted human single-rooted teeth were selected; 25 teeth for each test group and five for each control group. After conducting conventional e...

Materials and methods: Between April 2000 and December 2012, we retrospectively investigated data from patients who were diagnosed with organic ED and performed penile prosthesis implantation (PPI). Of the 239 patients, 235 patients were included in the study. Four patients who were operated on for transsexuality were excluded from the study. All patients were divided into two groups; group 1 i...
