Efron's Monte Carlo bootstrap algorithm is shown to cause degeneracies in Pearson's r for sufficiently small samples. Two ways of preventing this problem when programing the bootstrap of r are considered. (Author)

Six different algorithms to generate widely different non-normal distributions are reviewed. These algorithms are compared in terms of speed, simplicity, and generality of the technique. The advantages and disadvantages of using these algorithms are briefly discussed. (Author)

A general factor analysis computer algorithm is briefly discussed. The algorithm is highly transportable with minimum limitations on the number of observations. Both singular and non-singular data can be analyzed. (Author/JKS)

A clustering algorithm which is tree-like in structure, and is based on user queries, is presented. It is compared to some existing algorithms and is found to be superior. (Author)

This article is a tutorial on writing a simulator--the example used is a casino. The nontechnical, step by step approach is designed to enable even non-programmers to understand the design of such a simulation. (Author)

Improvements of the Gaussian quadrature in conjunction with the Newton-Raphson iteration technique (TM 000 789) are discussed as effective methods of calculating the bivariate normal correlation coefficient. (CK)

Sketchcode is a metaprograming pseudo-language documentation technique intended to simplify the process of program writing and debugging for both high and low-level users. Helpful hints and examples for the use of the technique are included. (CMV)

The design of programs to search large document data bases is discussed with regard to the use of compression coding combined with adoption of word fragments as the basic language elements. An algorithm is described for determination of a set of almost equifrequent fragments. Its efficiency is tested. (23 references) (Author)

Results of analysis of 1,377 spelling error forms including three categories of spelling errors (consonantal, vowel, and sequential) demonstrate that majority of spelling errors are highly predictable when set of predefined rules based on phonological and sequential considerations are followed algorithmically. Eleven references and equivalent…

Considered in this paper are a mathematical discussion and an algorithm, and a computer program for Fisher's test. (Author)

ORDMET is applicable to structures obtained from additive conjoint measurement designs, unfolding theory, general Fechnerian scaling, types of multidimensional scaling, and ordinal multiple regression. A description is obtained of the space containing all possible numerical representations which can satisfy the structure, size, and shape of which…

The main purpose of this paper is to describe and discuss the mechanism and properties of a computer program which can achieve an analogous segmentation of letter strings on punched cards. (Author)

Useful programming tricks are suggested to allow the reduction of many equations and non-polynomial-like expressions and the subsequent application of the mathematical algorithms. (Author)

Addressing the problem of protecting confidential information and data stored in computer databases from access by unauthorized parties, this paper details coding schemes which present such astronomical work factors to potential code breakers that security breaches are hopeless in any practical sense. Two procedures which can be used to encode for…
