KEY STAGES OF STATISTICAL METHODS DEVELOPMENT

abstract 0971403086 issue 97 pp. 1205 – 1229 31.03.2014 ru 1341
The first statistical publication – the Fourth Book of Moses, “Numbers” in the Old Testament. We trace the development of ideas about the statistics until the twentieth century. The present stage of statistical methods began with parametric statistics by Pearson, Student, Fisher. Scientometrics of statistical researches provides an indication of the accumulated results. Nonparametric statistics appeared in the 1930s, applied statistics in our country - at the turn of 1970-80. We have discussed what gives applied statistics to national economy. Also we have told briefly about the history of statistical methods in Russia (until Kolmogorov's time)

GRAVITATIONAL WAVES AND STATIONARY STATES OF QUANTUM AND CLASSICAL SYSTEMS

abstract 0971403090 issue 97 pp. 1299 – 1322 31.03.2014 ru 1211
In this paper, we consider gravitation theory in multidimensional space. The model of the metric satisfying the basic requirements of quantum theory is proposed. It is shown that gravitational waves are described by the Liouville equation and the Schrodinger equation as well. The solutions of the Einstein equations describing the stationary states of arbitrary quantum and classical systems with central symmetry have been obtained. Thus, it is proved that atoms and atomic nuclei can be represented as standing gravitational waves

GRAVITATIONAL WAVES AND EMERGENCE PARAMETER OF CLASSICAL AND QUANTUM SYSTEMS

abstract 0971403092 issue 97 pp. 1342 – 1367 31.03.2014 ru 2138
It was established that the Fermi-Dirac statistics, Bose-Einstein and Maxwell-Boltzmann distribution can be described by a single equation, which follows from Einstein's equations for systems with central symmetry. Emergence parameter of classical and quantum systems composed by the rays of gravitational waves interacting with gravitational field of the universe has been computed

EINSTEIN, SCHROEDINGER, AND ATOM

It is shown that gravitational waves are described by the Liouville equation and the Schrodinger equation as well. The solutions of the Einstein equations describing the stationary states of arbitrary quantum and classical systems with central symmetry have been obtained. Einstein’s atom model has been developed, and proved that atoms and atomic nuclei can be represented as standing gravitational waves

PROBABILISTIC-STATISTICAL METHODS IN KOLMOGOROV’S RESEARCHES

abstract 0981404011 issue 98 pp. 156 – 178 30.04.2014 ru 1467
From a modern point of view we have discussed Kolmogorov’s researches in the axiomatic approach to probability theory, the goodness-of-fit test of the empirical distribution with theoretical, properties of the median estimates as a distribution center, the effect of "swelling" of the correlation coefficient, the theory of averages, the statistical theory of crystallization of metals, the least squares method, the properties of sums of a random number of random variables, statistical control, unbiased estimates, axiomatic conclusion of logarithmic normal distribution in crushing, the methods of detecting differences in the weather-type experiments

THE INVESTIGATION SOLVABILITY OF THE SECOND BOUNDARY VALUE PROBLEM FOR PARTIAL DIFFERENTIAL EQUATION WITH INVOLUTORY DEVIATIONS IN THE LOWEST TERMS

abstract 0981404022 issue 98 pp. 296 – 306 30.04.2014 ru 1497
In this article we consider the problem of solvability oа second boundary value problem for the model equation in partial derivatives with involutive deviation in the lowest terms. The investigation is based on a variable separation method

THE BOUNDARY VALUE PROBLEM FOR MIXED EQUATION WITH PERPENDICULAR LINES OF TYPE ALTERATION

abstract 0981404023 issue 98 pp. 307 – 317 30.04.2014 ru 989
The non-local boundary value problem for the second order mixed parabolo-hyperbolic equation with the non-smooth conditions of conjugation has been examined. The uniqueness and the existence of the solution for this problem have been proved

TO THE QUESTION OF VALUE DISTRIBUTION OF THE SUMS OF ABELIAN GROUP’S AND SHORT EXPONENTIAL TRIGONOMETRIC SUMS

abstract 0981404058 issue 98 pp. 785 – 798 30.04.2014 ru 1489
Theorems of the value distribution of the sums of Abelian Group’s characters and short exponentail triginimetric sums are proved in this article. Asymptotic formulas of these sums’ fractional moments are proved

TO THE QUESTION OF ELECTROMAGNETIC WAVES RADIATION

abstract 0981404074 issue 98 pp. 1004 – 1024 30.04.2014 ru 1647
The article discusses the question of the essence of radiation of electromagnetic waves of different sources and questioned the reliability of its description by J.Maxwell in the form of alternating electric and magnetic fields. It justifies the formation of an electromagnetic wave in the form of a wave of compression-decompression in surrounding electromagnetic photon field with a flux of photons of different frequencies emitted by different sources or antenna

STATISTICAL ESTIMATION FOR THE GROUPED DATA

abstract 0981404080 issue 98 pp. 1113 – 1133 30.04.2014 ru 1068
The probabilistic model of grouping data (including multidimensional data) is described. We have also generalized Euler-Maclaurin’s formulas. With its help Sheppard’s corrections and corrections on grouping for correlation coefficient are received. We have found and studied asymptotical corrections on grouping data generally. Accuracy of approach has been estimated
