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)

The relationships between speech parameters and speech intelligibility of 40 severely to profoundly hearing-impaired adults were studied. Regression analysis revealed that speech intelligibility was predicted by a cognate-pair voice-onset-time difference measure and a measure of the stability of the volume-velocity rise time. (Author/JDD)

Investigates the theory that differences in well-being and emotional distress may be a function of gender-role socialization--especially the masculine sex role orientation. Findings indicate that sex role socialization is related to differences in occupational strain and coping, and that the masculine orientation has adaptive significance for the…

Canonical analysis of two convex polyhedral cones involves looking for two vectors whose square cosine is a maximum. New results about the properties of the optimal solution to this problem are presented. The convergence of an alternating least squares algorithm and properties of limits of calculated sequences are discussed. (SLD)

In response to the above article by Meador et al., shows that graduate faculty ratings reflect total departmental publication performance rather than average research productivity. Hence, such ratings are a poor proxy for the dependent variable when modeling research output per faculty member. (MLF)

Analyzes three SAT data sets to address whether private high schools have higher completion and college enrollment rates than public high schools. Indicates a consistent advantage for public high schools with respect to SAT math attainment. In general, school effects outweigh ethnicity, gender, and social class in SAT outcome measures. (CJS)

The Reasons for Living Inventory was completed by 95 Black and 132 White male and female students at a predominantly White southern university. Female subjects had a greater fear of, and objection to, suicide. Blacks scored higher than Whites in reasons for living. (DM)
