sickle cell disease is a genetic haemoglobinopathy with consequent haemolysis and anaemia. it is of interest to study its effect on red cell indices beside haemoglobin concentration.the objective of the study is to determine the values of red cell indices in preschool-age children with sickle cell anaemia.we conducted a cross-sectional study including 97 children with sickle cell anaemia aged s...

We give some characterizations of the exponential distribution based on the distributional properties and the expected values of record values; the index of record values has the geometric distribution.

Consider k success counts from a binomial distribution with unknown N and success probability p. We consider the problem of estimating N. By integrating the likelihood for Nand p over a beta density for p, we obtain the beta-binomial distribution which results in stable and reasonably efficient estimators of N, which compare favorably with and are often better than the estimates introduced by O...

Distribution Extents (DE) of order k for a sample {x1, x2,... xn} of a non-negative stochastic variable X can be defined as

The known estimation and simulation methods for multivariate t distributions are reviewed. A review of selected applications is also provided. We believe that this review will serve as an important reference and encourage further research activities in the area.

Introduction: Musculoskeletal growth is variable during adolescent period and reaches its maximum by 18 years, whereas hemopoietic parameters reach adult values by 15 years. After adolescence period, the blood parameters may vary with nutrition and built of the individual. The purpose of this study was to find out any correlation between anthropometric and hematological parameters after the ado...

a total of 1695 blood samples collected from ten ethnically distinct populations of iran (turks and kurds of rezaieh, lurs, aabolis, baluchis, turks and kurds of shrvan, zoroastrians, tehranis, and kermanis) were examined for six polymorphic red cell enzyme systems, namely red cell acid phosphatase (ap), adenylate kinase (ak), phosphoglucomutase (pgm1), esteraxe d (esd), adenosine deaminase (ad...
