TESTING OF HOMOGENEITY OF PAIRED SAMPLES

abstract 1231609047 issue 123 pp. 708 – 726 30.11.2016 ru 444
The article begins with the letter of the chief engineer of chemical plant near Moscow. He requests to analyze of data by means of modern statistical methods and give an opinion on the presence (or absence) of the relationship between the two methods of determining the viscosity of the mastic. For each of the batches of mastic It was presented two numbers - the viscosity measurement results of the two methods. These numbers form two paired samples. We want to install, give whether two specific methods similar results. The true values of viscosity in different batches are not equal. Their difference is not allows us to combine the results of the first measurement method in first sample, the results of the second method - in the second sample, as we can do in the case of testing the homogeneity of two independent samples. For solutions to this problem we discuss four statistical criterions, based on a study of the differences between corresponding values in two paired samples. We test the hypothesis of equality 0 of median of these differences (sign test) and of equality 0 of the mathematical expectation of these differences. Hypothesis of testing of equality of the distribution functions of two paired samples is reduced to the hypothesis of symmetry of the distribution function of these differences with respect to 0. In the alternative of the shift is proposed to use the Wilcoxon signed rank criterion. In the total alternative is proposed to use criterion of the omega-square type which is developed by the author of this article

THE APPROACHES TO THE DEVELOPMENT OF ORGANIZATIONAL-ECONOMIC SUPPORT FOR CONTROL PROBLEMS IN THE AEROSPACE INDUSTRY

abstract 0991405005 issue 99 pp. 73 – 100 30.05.2014 ru 1402
For strategic and operational management tasks in the aerospace industry we use a variety of organizational-economic models and methods. Their set is called an organizational-economic support. In this article we discuss the approaches to the development of adequate organizational-economic support in the aerospace industry. In particular, we consider the problems of estimation of the effectiveness and management of innovation-investment projects to create aviation and space technology

THE ASYMPTOTIC INFORMATION CRITERION OF NOISE QUALITY

abstract 1161602100 issue 116 pp. 1564 – 1613 29.02.2016 ru 0
Intuitively everyone understands that noise is a signal in which there no information is, or which in practice fails to reveal the information. More precisely, it is clear that a certain sequence of elements (the number) the more is the noise, the less information is contained in the values of some elements on the values of others. It is even stranger, that noone has suggested the way, but even the idea of measuring the amount of information in some fragments of signal of other fragments and its use as a criterion for assessing the degree of closeness of the signal to the noise. The authors propose the asymptotic information criterion of the quality of noise, and the method, technology and methodology of its application in practice. As a method of application of the asymptotic information criterion of noise quality, we offer, in practice, the automated systemcognitive analysis (ASC-analysis), and as a technology and software tools of ASC-analysis we offer the universal cognitive analytical system called "Eidos". As a method, we propose a technique of creating applications in the system, as well as their use for solving problems of identification, prediction, decision making and research the subject area by examining its model. We present an illustrative numerical example showing the ideas presented and demonstrating the efficiency of the proposed asymptotic information criterion of the quality of the noise, and the method, technology and methodology of its application in practice

THE DEVELOPMENT AND MANAGEMENT DECISION-MAKING

abstract 1301706041 issue 130 pp. 567 – 597 30.06.2017 ru 184
The article is devoted to discussion of modern views on management decisions. We have released several bulk textbooks on the theory of decision-making. This article discusses several key aspects of this theory: a comparison of approaches to decisionmaking, the pitfalls of voting, and the methodology of decision-making, management responsibility. We have considered a simple example of a problem of decision-making in the management of the organization: selection a model of a new car to run into a series. Criteria for making a decision, which put forward by the four experts-theorists, contradicted each other. The Board of Directors decided to issue a vote. We have considered the "reefs" of voting. In the production and realization of administrative decisions we distinguish four levels. The first and most important level, which determine the success or failure of administrative activity is methodological. We discuss the levels of production and realization of administrative decisions. We give some examples where methodological errors lead to wrong management decisions. For example, a call to "maximum profit at the lowest cost" is quite common in the speeches and orders of a general nature. However, it is mistaken. Practice of development, adoption and implementation of solutions is based on a few basic concepts: Who makes the decisions? The procedure for preparation of the solution (the regulations). Objectives. Resources. The risks and uncertainties. Criteria for estimating decisions. The manager has his responsibility for the decisions taken. Volition of manager - the basis of management

THE DIVERSITY OF CONTROLLING DOMAINS AND INSTRUMENTS

abstract 1231609046 issue 123 pp. 688 – 707 30.11.2016 ru 179
In modern conditions of quantitative and qualitative degradation of science in general and economics in particular, especially in our country, the scientific direction of "Controlling" stands out not only for its activity, but also the rapid intensive and extensive growth. This work is the summary of the main publications of scientific results on controlling obtained at the Laboratory of economicmathematical methods in controlling of Scientific and Educational Center "Controlling and management innovations" of Bauman Moscow State Technical University. We discuss the concept of "method", "tool", "mechanism", "algorithm" in relation to the Controlling. Adequate use of these terms is necessary for the formulation of sound scientific results, and to provide their perception of the scientific community. Innovations in the field of management in industry and other sectors of the economy based, in particular, on the use of new adequate organizational and economic methods. Controlling in this area - it is the development of relevant management procedures used and the newly established (implanted) organizational and economic methods to the task. Development, systematization and application of modern mathematical tools of controlling are the main theme of our work. We have considered the problems of controlling new areas - controlling risks, quality controlling, controlling organizational and economic support for control tasks in the aerospace industry, controlling research activities. We have also obtained new scientific results in controlling personnel and ecological safety controlling

THE LIMIT THEORY OF THE SOLUTIONS OF EXTREMAL STATISTICAL PROBLEMS

abstract 1331709045 issue 133 pp. 579 – 600 30.11.2017 ru 407
Many procedures of applied mathematical statistics are based on the solution of extreme problems. As examples it is enough to name methods of least squares, maximum likelihood, minimal contrast, main components. In accordance with the new paradigm of applied mathematical statistics, the central part of this scientific and practical discipline is the statistics of non-numerical data (it is also called the statistics of objects of non-numerical nature or non-numeric statistics) in which the empirical and theoretical averages are determined by solving extreme problems. As shown in this paper, the laws of large numbers are valid, according to which empirical averages approach the theoretical ones with increasing sample size. Of great importance are limit theorems describing the asymptotic behavior of solutions of extremal statistical problems. For example, in the method of least squares, selective estimates of the parameters of the dependence approach the theoretical values, the maximum likelihood estimates tend to the estimated parameters, etc. It is quite natural to seek to study the asymptotic behavior of solutions of extremal statistical problems in the general case. The corresponding results can be used in various special cases. This is the theoretical and practical use of the limiting results obtained under the weakest assumptions. The present article is devoted to a series of limit theorems concerning the asymptotics of solutions of extremal statistical problems in the most general formulations. Along with the results of probability theory, the apparatus of general topology is used. The main differences between the results of this article and numerous studies on related topics are: we consider spaces of a general nature; the behavior of solutions is studied for extremal statistical problems of general form; it is possible to weaken ordinary requirements of bicompactness type by introducing conditions of the type of asymptotic uniform divisibility

THE METHOD FOR HYPOTHESIS TESTING BASED ON SET OF SMALL SAMPLES AND ITS APPLICATION IN THE THEORY OF STATISTICAL CONTROL

abstract 1041410003 issue 104 pp. 43 – 57 30.12.2014 ru 979
We have proposed the method for testing of independence of two alternative variables on the basis of statistics of non-numeric data. The method is aimed at application in problems of statistical quality control. Testing of independence is based on set of small samples, i.e., in the Kolmogorov’s asymptotics, when the number of unknown parameters of the distribution increases in proportion to the data size

THE NEW CHRONOLOGY OF THE WORLD HISTORY AND THE RUSSIAN HISTORY AS THE BASIS OF STATE-PATRIOTIC OUTLOOK

abstract 1201606003 issue 120 pp. 60 – 85 30.06.2016 ru 276
The relationship of Mathematical Statistics (wider - Mathematical methods of research) and history is multifaceted. In our opinion, the history of mathematical statistics is an integral part of this mathematical discipline. We have given a review of our works on the history of statistical methods. The role of mathematical statistics for the history is very important. In this article, we restrict ourselves to the questions of chronology. For centuries, the chronology is considered as a part of applied mathematics. The main problem is that the whole "common" concept of the Russian and the World history as a whole presented in textbooks was faked by the opponents of Russia after the collapse of the global Empire (Russian kingdom) in the early 17th century - 400 years ago. The stories about historical events are the information weapon. It was used by the new rulers to suppress the resistance of the vanquished. A new mathematical and statistical chronology of general and Russian history, which was built by a scientific team led by Academician Fomenko, has been helpful for the discussion about the current economic and political problems of relations between Russia and the West in the XXI century. In our opinion, the new chronology of the World and Russian history should be one of the foundations of state-patriotic ideology and deriving practical solutions. The purpose of this article is to give the initial idea of the new chronology from this point of view
