Statistical analyses of scores on subtests of the Intelligence Test for Visually Impaired Children were done for two groups of children, either with or without usable vision. Results suggest that the battery has differential factorial and predictive validity. (Author/DB)

This study, involving 54 first-grade children, found that correlations between decoding and phonological awareness were generally much higher than correlations obtained for measures of decoding and verbal and nonverbal intelligence. Several phonological awareness tasks identified good and poor decoders, with approximately 80-90% accuracy. (DB)

Describes an expected precision (EP) measure designed to predict document retrieval performance. Highlights include decision theoretic models; precision and recall as measures of system performance; EP graphs; relevance feedback; and computing the retrieval status value of a document for two models, the Binary Independent Model and the Two Poisson…

A factor analysis was conducted on Home Observation for Measurement of the Environment (HOME) item scores of low-income black and white urban mothers of infants 13 to 30 months of age to determine the extent to which the existing subscales were evident in this factor analysis.

Estimated age-adjusted Wechsler Adult Intelligence Scale-Revised intelligence quotient (IQ) scores using linear regression techniques and continuous norming of two samples of psychiatric inpatients (total N=150) in Veteran's Administration hospital. Results support use of estimation procedure in clinical and research settings desiring brief but…

Two sophisticated--autoregressive integrated moving average (ARIMA), straight-line regression--and two naive--simple average, monthly average--forecasting techniques were used to forecast monthly circulation totals of 34 public libraries. Comparisons of forecasts and actual totals revealed that ARIMA and monthly average methods had smallest mean…

This paper describes a procedure for smoothing the proportions of a double-entry expectancy table which might be used in higher education admissions advising or other functions. The product of the smoothing procedure is a nomograph, a medium for displaying expectancies which provides pairs of individual values for two predictor variables rather…

This report investigates the appropriateness of using the General Technical (GT) composite of the Armed Services Vocational Aptitude Battery (ASVAB) as a reenlistment criterion. Three aptitude measures, all ASVAB composites, were compared to measures of proficiency in job performance: the Armed Forces Qualification Test (AFQT), the GT, and the…

The study applying the theory of reasoned action found that special education teachers' (N=28) intentions to structure integration opportunities were predicted from measures of attitude and subjective norm; actual reported structuring of opportunities was weakly predicted by intention and the antecedent of attitude. (Author/DB)

A model is proposed for the clinical synthesis of data from psychological tests of persons with visual impairments. The model integrates the concepts of the ideal type and Bayesian probability and compares actual test scores with ideal scores through use of a pattern similarity coefficient. A pilot study with Business Enterprise Program operators…

The Mantel-Haenszel (MH) procedure attempts to identify and quantify differential item performance (item bias). This paper summarizes the MH statistics, and identifies the parameters they estimate. An equivalent procedure based on the Rasch model is described. The theoretical properties of the two approaches are compared and shown to require the…

Recent research suggests that alcoholic inpatients' performance on neuropsychological tests is predictive of their drinking status following discharge from alcohol rehabilitation programs, although no single test itself has been predictive of relapse. This study seeks to develop a ecologically relevant memory test that would predict relapse and…

For over 50 years, the overwhelming weight of evidence has been that subjects are able to make use of partial information when responding to multiple-choice items. The subject chooses the alternative which has given rise to the lowest mismatch, except that if this minimum mismatch is larger than some threshold, the question is left unanswered.…

This paper discusses the principles underlying discriminant analysis and constructs a simulated data set to illustrate its methods. Discriminant analysis is a multivariate technique for identifying the best combination of variables to maximally discriminate between groups. Discriminant functions are established on existing groups and used to…

An empirical method called Predicted Error Sum of Squares (PRESS) is advanced and studied. This method is used to examine the cross-validated prediction accuracies of some popular algorithms for weighted predictor variables. The weighting methods that were considered were ordinary least squares, ridge regression, regression on principal…
