Conjunctive item response models are introduced such that (a) sufficient statistics for latent traits are not necessarily additive in item scores; (b) items are not necessarily locally independent; and (c) existing compensatory (additive) item response models including the binomial, Rasch, logistic, and general locally independent model are…

The results obtained from two basic types of pre-equatings of tests were compared: the item response theory (IRT) pre-equating and section pre-equating (SPE). The simulated data were generated from a modified three-parameter logistic model with a constant guessing parameter. Responses of two replication samples of 3000 examinees on two 72-item…

Methods for meta-analysis have evolved dramatically since Gene Glass first proposed the term in 1976. Since that time statistical and nonstatistical aspects of methodology for meta-analysis have been developing at a steady pace. This guide is an attempt to provide a practical introduction to rigorous procedures in the meta-analysis of social…

This report examines the poverty status of persons in 1984 and 1985 using the complete panel file of the 1984 Survey of Income and Program Participation (SIPP) and compares those findings to poverty estimates based on the Current Population Survey (CPS). Although the CPS is used to obtain official estimates of persons in poverty, SIPP captures the…

This report is about the problem of making transition or enrollment rate gains comparable. It is shown that measures based on the proportions themselves, i.e. the difference between proportions, the proportion ratio and the residual gain ratio do not make the gains comparable. Instead a non-linear transformation has to be done. Two such…

Based on an analysis of 46 small geographic areas, birth weight statistics were related to variables of income, home maintenance, medical and dental care, and aid to dependent children. It was suggested that birth weight statistics may be more effective than infant mortality statistics for many purposes where death data are now used. (EH)

This study examined the relationship between operating tax rates and selected socioeconomic variables for Illinois school districts. Districts were separately ranked by operating tax rates and then divided into four equal quartiles--low tax effort, low medium tax effort, high medium tax effort, and high tax effort.

Twenty-one tables display data on library materials, staff, finances, and services. Analysis of…

Three procedures used to control Type I error rate in stepwise regression analysis are forward selection, backward elimination, and true stepwise. In the forward selection method, a model of the dependent variable is formed by choosing the single best predictor; then the second predictor which makes the strongest contribution to the prediction of…

The purpose of the book is to estimate the cost of providing special education and training to different groups of handicapped children and youth, and to compare the costs with ordinary education.
