The study of the homogeneity of the selections by non- parametric tests

Summary/Abstract: In many practical problems, same as in studies of the phenomena of different scientific and theoretical fields and disciplines, particularly economic ones, comes up the need for optimal use of observed data, which, under certain conditions, cannot methodically cover the whole population. In practice, assembling and study of such statistics finds great use, which helps checking the accuracy of the information collected and processed. Too often, such efforts converge in the study of homogeneity of data, the most important in studying the homogeneity phenomenon, meaning the Random Size. The study of the homogeneity of the selections is conducted by non-parametric control of the hypotheses set by building tests for the case of one or several solutions. Many authors have attempted to construct appropriate tests for the control of non-parametric hypothesis. Their theoretical studies include asymptotic problems associated with these statistics allowing the use of similar formulas for nonsmall volumes of selections. In this paper we analyze some of the tests constructed by different authors and there is an attempt to compare two of these tests.
