This study compared double cross-validation replication predictive accuracies of six types of factor scores with full-rank data by utilizing data in which classroom achievement was predicted from affective and cognitive variables. Prediction was significantly more accurate for factor scores than for full-rank data. (Author/CP)

Forty trainable mentally retarded students were concurrently administered the Stanford Scale and the Wide Range Achievement Test (WRAT). WRAT reading, spelling and arithmetic subtests were regressed on Stanford intelligence quotients. Predictions were statistically valid. Derived regression equations are reported. (Author/CP)

A variety of algorithms for analyzing covariance structures are considered. Additionally, two methods of estimation, maximum likelihood, and weighted least squares are considered. Comparisons are made between these algorithms and factor analysis. (Author/JKS)

A Swedish study to ascertain factors associated with work after retirement indicates that most of the survey sample of 534 men and women aged 60-75 had positive attitudes toward continued work, were reluctant to retire, and had positive perceptions of retirees and their social contacts. (MF)

Supports multiple regression analysis as a tool for isolating the impact of newspaper content on newspaper sales. (RL)

Concludes that humanism in teachers is related to reporting fewer unresolvable conflicts with pupils and that pupil control ideology and subsequent teacher control behavior (the referring of pupils to the administration for disciplinary action) are related. (Author/IRT)

Contrary to Anderson (EJ 187 936), his rule for equation identification is a necessary but not sufficient condition; furthermore, the choice of two-stage or ordinary least squares depends on results and not on methodological properties of estimators. Modification of Anderson's rule and a means for choosing between estimates is offered. (Author/CP)

The Sixteen Personality Factor Questionnaire, Gordon Personal Profile, and Gordon Personal Inventory were administered to 151 male and female high school students. Multiple regression analysis indicated that the personality scales of each test could be predicted from the scales of the other tests. (Author/JKS)

A Monte Carlo simulation was employed to determine the accuracy with which the shrinkage in R squared can be estimated by five different shrinkage formulas. The study dealt with the use of shrinkage formulas for various sample sizes, different R squared values, and different degrees of multicollinearity. (Author/JKS)

A total of 15 acute schizophrenics, 11 acute psychotic depressives, and 15 normal subjects completed a multitrial free-recall task. Results indicated that with lists of relatively high semantic content, the recall impairment displayed by schizophrenics and depressives stems mainly from an inability to completely use perceived structuring of the…

Multiple regression is used to discover interconnections between IQ and vocabulary test scores as one variable, and socioeconomic factors as the other. Results show total variance as explained by predictors is never more than eight per cent, indicating differences in IQ scores are not attributable to environmental factors. (RW)

Problems in measuring change abound. For many purposes, a pretest score is best treated as any other measure obtained at the time of the pretest. Where appropriate, regression analyses that treat the pretest no differently from other independent variables, and the posttest as the dependent variable avoid many difficulties introduced by gain…

Multiple regression analyses are used to determine the relative importance of 49 factors to job involvement in a study of 441 scientists and engineers. Of particular importance are career and personality factors. (Author)

Multiple regression analysis of data regarding college students' oral proficiency in using the present subjunctive after residence in a Spanish-speaking country found a significant positive relationship between length of residence and subjunctive proficiency, and a nonstatistically significant positive relationship between formal study and…

Examines risk factors for sudden infant death syndrome based on Swedish births between 1983 and 1985. Results indicate that maternal smoking doubles the risk of infant death, and infants of smokers also died sooner. The more the mother smoked the more likely her infant was to die. (JS)
