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)

The use of statistical methods in the design and analysis of discrete algorithms is explored. The introductory chapter contains a literature survey and background material on probability theory. In Chapter 2, probabilistic approximation algorithms are discussed with the goal of exposing and correcting some oversights in previous work. Chapter 3…

A method for predicting freshman performance based on high school grades allows calculation of any student's likely grades in a similar university course. The method is contrasted with several more traditional predictive methods and examined in a study of 3,734 University of Western Australia students. (MSE)

Recent developments in econometrics that are relevant to the task of estimating costs in higher education are reviewed. The relative effectiveness of alternative statistical procedures for estimating costs are also tested. Statistical cost estimation involves three basic parts: a model, a data set, and an estimation procedure. Actual data are used…

An approach is described that reveals the hierarchical test structure (HTS) based on the cognitive demands of the test items, and conducts a linear trait modeling by using the HST elements as item difficulty components. This approach, referred to as the Hierarchical Latent Trait Approach (HLTA), employs an algorithm that allows all test items to…

Evaluates the validity of using circulation data as the index to the total utilization of a library collection and tests the hypothesis that the proposed mixture of Poisson distributions can describe and predict various use distribution. Seven statistical analysis listings, six algorithms, 20 tables, and 43 references are provided. (Author/RBF)
