Proposes a marginal Bayesian estimation procedure to improve item parameter estimates for the three parameter logistic model. Computer simulation suggests that implementing the marginal Bayesian estimation algorithm with four-parameter beta prior distributions and then updating the priors with empirical means of updated intermediate estimates can…

Approaches the development of the algorithm from a holistic, spiraling perspective in which students can avoid many of the common mistakes and misunderstandings associated with long division. (CCM)

Examines the use of stochastic frontier estimation of constant elasticity of substitution (CES) cost function to measure differences in efficiency among British universities. (Contains 28 references.) (PKP)

Presents a case study that calculates the reduction of the time needed for a Web page to be fully downloaded and delivered to the user. Topics include bandwidth; HTTP; data transfer; algorithms for compression and decompression of Web pages; and reducing the size of hypertext data. (Author/LRW)

This paper describes how a constraint dependency grammar (CDG) parser performs a syntactic analysis of a single sentence (as part of a speech recognition system). The paper extends an existing CDG (developed by H. Maruyama) to process a lattice or graph of sentence hypotheses instead of separate text strings. The paper also describes how the CDG…

The interest in the application of large-scale adaptive testing for secure tests has served to focus attention on issues that arise when theoretical advances are made operational. Many such issues in the application of large-scale adaptive testing for secure tests have more to do with changes in testing conditions than with testing paradigms. One…

Looks for a method to formulate algorithms useful for the synthesis of Czech in machine translation where the point of departure for the synthesis can be more or less identical with the semantic representation. (Author/PF)

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…

This article examines whether or not we are preparing our children to cope with change by teaching them to think. (PB)

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)

Designs for sequential sampling procedures that adapt to cumulative information are discussed. A familiar illustration is the play-the-winner rule in which there are two treatments; after a random start, the same treatment is continued as long as each successive subject registers a success. When a failure occurs, the other treatment is used until…

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)

Monte Carlo procedures were used to investigate the properties of a nonmetric multidimensional scaling algorithm when used to scale an incomplete matrix of dissimilarities. Recommendations for users wishing to scale incomplete matrices are made. (Author/RC)
