one of recent developments in modern societies is the evolution in the structure of power division in the family and changes in reciprocal actions between wife and husband. this research aims to study the factors affecting distribution of power in the family by using the theories of: social capital, valuable resources, and sociability of gender. the data has been collected through survey method...

The beta-binomial distribution is resulted when the probability of success per trial in the binomial distribution varies in successive trials and the mixing distribution is from the beta family. For experiments with binary outcomes, often it may happen that observations exhibit some extra binomial variation and occur in clusters. In such experiments the beta-binomial distribution can generally ...

the present checklist is a compilation of the eupodoid mites of iran using published records and original data from recent researches. it contains 19 species belonging to 13 genera and five families. family cocceupodidae jesionowska, 2010 (because of moving the genera to a new family) and two species i.e. foveacheles (foveacheles) cegetensis zacharda, 1983 and linopodes antennaepes banks, 1894 ...

In this paper, for an odd prime p such that p ≡ 3 mod 4, odd n, and d = (pn +1)/(pk +1)+ (pn −1)/2 with k|n, the value distribution of the exponential sum S (a, b) is calculated as a and b run through Fpn . The sequence family G in which each sequence has the period of N = pn − 1 is also constructed. The family size of G is pn and the correlation magnitude is roughly upper bounded by (pk + 1) √...

The unimodal distributions are frequently used in the theorical statistical studies. But in applied statistics, there are many situations in which the unimodal distributions can not be fitted to the data. For example, the distribution of the data outside the control zone in quality control or outlier observations in linear models and time series may require to be a bimodal. These situations, oc...
