Engineering approach of Statistics Processing for the Statistical Expert System
Korean Journal of Applied Statistics, volume 3, issue 1, 1990, Pages 1~9
Engineering approach of statistics processing is defined for the statistical expert system. First, the engineering approach requirement are conceptualized by using an artificial intelligence in statistics, with the extensions being additional statistical knowlege engineering such as software engineering, optinal relationships, and the generalization abstraction. The methodology produces statistical expert system designes that are not only accurate representations of reality but also enough to accommodate future processing requirements. It also representions of knowledge that must be constructed, using the extended engineering processing model conceptualization and proposed engineering approach of the problem.
Nonparametric test for ordered alternatives in multifactor designeds
Korean Journal of Applied Statistics, volume 3, issue 1, 1990, Pages 11~25
The objective of this paper is to propose a nonparametric distribution-free test for ordered alternatives in k crossed factor designs by using the concepts of combined factor and within-blocks ranks. We investigate the asymptotic normality of the proposed test statistic and the Pitman efficiencies. We also compared the small empirical powers of the tests considered in this paper by Monte Carlo study. Thus we can conclude that the proposed test is efficient and robust for the underlying distribution.
A study on the efficient sample design and the error in the statistical survey
Korean Journal of Applied Statistics, volume 3, issue 1, 1990, Pages 27~46
In this paper, wer propose many problems by analyzing the various currently statistics, propose the basic principal for the more precise performance of sample survey, and at the same time propose the method(principal) for detecting and manipulationg the source of error. Finally, we are to improving the statistical reliability and increasing the user's convenience by standardizing the statistical reporting form.
Mechanics of orthogonal regression
Korean Journal of Applied Statistics, volume 3, issue 1, 1990, Pages 47~58
Orthogonal regression is reviving due to the current development of software to control robotized coordinate measuring machines. Known features of orthogonal regression are summarized and geometry of the problem is interpreted in terms of equilibrium of force. A class example is given.
Operating characteristics of a subset selection procedure for selecting the best normal population with common unknown variance
;Shanti S. Gupta;
Korean Journal of Applied Statistics, volume 3, issue 1, 1990, Pages 59~78
The subset selection approach introduced by Gupta plays an important role in the multiple decision procedures. For the normal means problem with common unknown variance, some operating characteristics of the selection procedure have been investigated via Monte Carlo simulation. Also some properties including efficiencies of the selection procedure are examined when the data are contaminated.
Comparisons of some subset selection procedures for K normal populations with unequal sample size
Korean Journal of Applied Statistics, volume 3, issue 1, 1990, Pages 79~87
The problem of selecting a nonempty subset of K(>2) normal means with unknown variances has been studies by many authors. But the comparisions of the properties and the efficiencies of the proposed subset selection procedures have not been carried out. Thus we investigate properties of the proposed procedures and compare their performances for various cases.
Balanced hypothesis testing for interactions of unbalanced case using analysis of means
Korean Journal of Applied Statistics, volume 3, issue 1, 1990, Pages 89~103
An analysis of mean procedure is presented for testing the significance of two factor interactions for unbalanced case. When at least one factor if at only two levels, the technique is the same as that of Ott(1967) and Nelson(1988) except that we have used the critical value by using the Sidak's multiplicative inequality. The technique can be extended to the case in which both factors more than two levels. Tables of critical values g(
) are given for
=0.05 and 0.01 ; (p, q) combinations satisfying
; and various degrees of freedom v. We present and prove the formula of the variance of the interactions for the n-way model.
A study on sequential test based on cumulative sum of statistics
Korean Journal of Applied Statistics, volume 3, issue 1, 1990, Pages 105~120
In this paper, a sequential test procedure is defined by using cumulative sum (CUSUM) of statistics. The properties as well as the efficiency of the CUSUM test are studied in comparison with the sequential probability ratio test (SPRT). It was shown that, the operating characteristic function and the average sample numbrer can be derived by Wald and Wiener process approximations. Also it was shown that the statistics used in the CUSUM test is determined to provide asymtotically equivalent efficiency compared to the SPRT. The efficiency of the CUSUM test and the SPRT are cpmpared by an example for some limited number of cases in the exponential distribution.
A Computer Intensive Method for Modern Statistical Data Analysis I ; Bootststrap Method and Its Applications
Korean Journal of Applied Statistics, volume 3, issue 1, 1990, Pages 121~141
Computer intensive bootstrap methods are studied as a tool of statistics. Practical calculation and theoretical justification problem of the methods in estimating the sampling distribution and construction confidence region of parameters are discussed through several examples. Statistical meaning of the methods are also considered.
