A theorem of Spjotvoll (1972) was used to determine and apply a confidence interval for the difference of two multiple correlations based on observations from a single sample. Spjotvoll's method of comparing regression functions is also applicable to a comparison of dependent multiple correlations, an unsolved problem posed by Hotelling in 1940.…

Ridge regression is an approach to the problem of large standard errors of regression estimates of intercorrelated regressors. The effect of ridge regression on the estimated squared multiple correlation coefficient is discussed and illustrated. (JKS)

Ridge regression is a technique used to ameliorate the problem of highly correlated independent variables in multiple regression analysis. This paper explains the fundamentals of ridge regression and illustrates its use. (JKS)

This study explored anomic and egoistic dimensions of contemplated suicide among voluntary and involuntary retired males. Results indicated a direct relationship between anomie and egoism on the one hand, and contemplation of suicide on the other. (Author)

Research on teacher survival rates during the first three years of the teaching experience indicate that scores on preadmission interviews are a useful predictor of survival in the early teaching years. (MJB)

Attempted to identify predictors of positive treatment outcome following behavioral marital therapy. The only variable that significantly predicted outcome at both posttest and follow-up was a measure reflecting traditional affiliation/independence patterns: couples with a highly affiliative wife and a highly independent husband were less likely…

Reports that with the increase in diagnosis of offenders across the nation, physicians and psychiatric personnel need to be aware of low testosterone as a possible indicator of hypo-sexuality and possible concurrent offending behavior. (Author/ABB)

The purpose of this paper is to calculate the upper limit of the correlation between normal and dichotomous variables. An empirically obtained correlation should be evaluated in view of this limit, instead of the usual limit of Pearson correlation. (Author)

Examines the effectiveness of selected assessment and screening procedures for identifying successful and unsuccessful participants in employment and training programs conducted by the Program for Assessment, Counseling, and Employment of the Young Men's Christian Association of Greater New York. (Author)

Examined the relationship between social and psychological correlates of youthful suicide victims and methods of lethality. The results suggest that a wide range of factors may be related to youthful intent and suicidal behavior, but only minor differences are observed among a single cohort of committers. (Author/BL)

Describes paper and pencil predictions of employee theft and examines studies of validity, reliability, and adverse impact of these tests. Results showed consistently positive correlations, but identified a variety of methodological differences which make the direct comparison of test validities suspect. (LLL)

Much analysis of the correlates of divorce fails to take into account the time dependency of this event with respect to marital duration. This paper focuses explicitly on the relationship between independent variables and the timing of divorce. Results indicated a perceptual problem model better describes the relationship between various variables…

Presents data on the relative frequency of felonies and misdemeanors by age and patterns of offenses for Dade County, Florida, in 1980 and 1982. The pattern of offenses by the elderly was varied. Age was a better predictor of offense rates than sex or race. (JAC)

Assessed Work Incentive Program (WIN) registrants using various aptitude tests and vocational interest surveys. Subjects (N=56) were females receiving Aid to Dependent Children. Results showed that learning ability, educational levels, and work-style preferences were useful in predicting success or failure in training or employment. (BH)
