Red cell distribution width (RDW), an electronically determined index of anisocytosis, was examined in 60 patients with sickle cell anemia (Hb SS), 28 patients with hemoglobin sickle cell (SC) disease, and seven patients with sickle cell-beta(+) thalassemia (S-thal). All patients were adults and in the steady state of their disease. The RDW was greater in sickle cell patients than in 39 healthy...

A test statistic based on population quantiles using sample order statistics is suggested. The quantiles of the test statistics are evaluated for generalized exponential distribution. Similar test statistic based on moments of sample order statistic is referred and the proposed test formula is compared with it. Between the pairs of the above models it is established that the test formula propos...

A procedure is derived for determining the values of the parameters of a multinomial distribution by means of the fiducial approach proposed by Fisher. By decomposing the involved probability (mass or density) functions, it is shown that the resulting fiducial distributions belong to the Dirichlet family.

This paper considers two flexible classes of omnibus goodness-of-fit tests for the inverse Gaussian distribution. The test statistics are weighted integrals over the squared modulus of some measure of deviation of the empirical distribution of given data from the family of inverse Gaussian laws, expressed by means of the empirical Laplace transform. Both classes of statistics are connected to t...

OBJECTIVE Acute cholecystitis is a common disease requiring accurate markers for diagnosis and proper treatment. The aim of this study was to investigate the role of red cell distribution width (RDW) in acute cholecystitis. MATERIAL AND METHODS 299 were included in the study. The subjects were divided into 2 groups; group 1 (n: 46) acute cholecystitis group and group 2 (n: 253) chronic cholec...

Background: Red cell distribution width (RDW) is a routine laboratory measure that could be used as a predictor of mortality in critically ill patients. Identification of patients at risk for mortality early in the course of PICU admission is an important step in improving the outcome. We aimed to assess the use of RDW as an early biomarker for outcome in pediatric critical illnesses. Methods:...

INTRODUCTION AND OBJECTIVES Red blood cell distribution width has emerged as a new prognostic biomarker in cardiovascular diseases. Its additional value in risk stratification of patients with chronic heart failure has not yet been established. METHODS A total of 698 consecutive outpatients with chronic heart failure were studied (median age 71 years [interquartile range, 62-77], 63% male, le...
