Various bounds for the r−weighted Gini mean difference of an empirical distribution are established.

The classification tree is commonly used in data mining for investigating interaction among predictors, particularly. The splitting rule and the decision trees technique employ algorithms that are largely based on statistical and probability methods. Splitting procedure is the most important phase of classification tree training. The aim of this study is to compare Gini and Twoing splitting rul...

We intend to point out the differences which exist between the classical Gini concentration coefficient and a proposed bipolarization index defined for an arbitrary random variable which have a finite support. In fact Gini's index measures only the "poverty degree" for the individuals from a given population taking into consideration their wages. The Gini coefficient is not so sensitive to the ...

BACKGROUND Positive greenness effects on health are increasingly reported, although studies on allergic outcomes remain limited and conflicting. We examined whether residential greenness is associated with childhood doctor diagnosed allergic rhinitis, eyes and nose symptoms and aeroallergen sensitisation using two combined birth cohorts (GINIplus and LISAplus) followed from birth to 10 years in...

BACKGROUND The purpose of the present study was to evaluate the inequality of geographical distribution of non-cardiac intensive care beds in Iran using the Gini coefficient. METHODS The population information of Iran's provinces in 2006 was obtained from The Statistical Center of Iran and the number of non-cardiac intensive care beds (including ICU, PostICU and NICU beds) in all provinces wa...

BACKGROUND Differences in Multiple sclerosis (MS) disease-modifying therapy (DMT) prescribing patterns between different groups of neurologists have not been explored. OBJECTIVE To examine concentrations of prescribing patterns and to assess if MS-specialists use a broader range of DMTs relative to general neurologists. METHODS We conducted a cross-sectional study using administrative claim...

We present the quantitative rest-frame B morphological evolution and galaxy merger fractions at 0.2 < z < 1.2 as observed by the All-wavelength Extended Groth Strip International Survey (AEGIS). We use the Gini coefficent and M20 to identify major mergers and classify galaxy morphology for a volume-limited sample of 3009 galaxies brighter than 0.4L∗B, assuming pure luminosity evolution of 1.3 M...
