The effectiveness of four different imputation procedures (mean, conditional mean, hot deck, and regression) was compared in a two-variable prediction system using a sample of 18,869 college students. Results show that the grand mean procedure is not appropriate for handling missing data. Conditions under which either the conditional mean or…

Sources of organizational learning were studied for 131 employees, 109 of whom were managers, who participated in projects with external consultants in a large public-transport company in Norway. A multiple regression analysis explained 69% of organizational learning as a function of attitude toward learning. Differences between managers and other…

Relationships between clients' Myers-Briggs Type Indicator (MBTI) scores and their career obstacles were investigated. Uses of MBTI are presented briefly. Subjects (N=118) were seeking career counseling; counselors administering the tests and rating clients were blind to the hypothesis. Results of a regression analysis are presented and discussed.…

Presents a replication of a model of student self-rated health initially proposed by Vingilis, Wade and Adlaf (1998). The original model is tested by a series of nested regression equations and path analysis. The results add support for the original model and are notable given that many items used to build the underlying constructs differ across…

A linear regression approach to determining the number of factors in factor analytic solutions is presented. It provides objectivity while producing the same results as the visual scree test. Experience with the method to date indicates that the results are consistent with visual solutions. (SLD)

Compares the odds ratio with the probability ratio (relative risk). These quantities arise, for example, in the analysis of educational and social science through logistic regression. (Author/SLD)

Discusses a regression exercise that uses real-life data, has proven interesting to students in all disciplines, and is rich to demonstrate a number of the central concepts of regression analysis. (Author/ASK)

The authors of the paper on growth mixture modelling (GMM) give a description of GMM and related techniques as applied to antisocial behaviour. They bring up the important issue of choice of model within the general framework of mixture modelling, especially the choice between latent class growth analysis (LCGA) techniques developed by Nagin and…

Purpose: Our objective in this analysis was to determine how the duration of caregiving interacts with key care demands (i.e., severity of problem behaviors) to influence the institutionalization of individuals suffering from dementia. Methods: We utilized multiregional data from 4,761 caregivers of individuals with dementia over a 3-year period.…

Purpose: This study examines the moderating effect of staff stability on the relationship between management practices used to empower nurse aides and resident outcomes in a multistate sample of nursing homes. An adaptation of Kanter's theory of structural power in organizations guided the framework for the model used in this study. Design and…

Probably the one "new" mathematical topic that is most responsible for modernizing courses in college algebra and precalculus over the last few years is the idea of fitting a function to a set of data in the sense of a least squares fit. Whether it be simple linear regression or nonlinear regression, this topic opens the door to applying the…

This paper investigates how students' collegiate athletic participation affects their subsequent labor market success. By using newly developed techniques in nonparametric regression, it shows that on average former college athletes earn a wage premium. However, the premium is not uniform, but skewed so that more than half the athletes actually…

This article examines the relationships among adolescent environmental behaviors and self-efficacy, knowledge, and attitudes. It was hypothesized that adolescents who demonstrate more proenvironmental attitudes are more likely to demonstrate proenvironmental behaviors. It was further hypothesized that perceived self-efficacy would have a…

The gendered division of household labor is more multifaceted than the allocation of paid work and domestic work. People also engage in volunteer work and informal support. I investigate the applicability of household labor allocation theories - specifically the time constraints, economic, and doing gender perspectives - to all unpaid work. I…

The roles of loss aversion and inhibition among alternatives are examined in models of the similarity, compromise, and attraction effects that arise in choices among 3 alternatives differing on 2 attributes. R. M. Roe, J. R. Busemeyer, and J. T. Townsend (2001) have proposed a linear model in which effects previously attributed to loss aversion…
