Addresses the use of missing cells in longitudinal research. Gives a sample educational situation involving cohorts and grade levels and uses multiple linear regression for the solution. Discusses applications of longitudinal research wherein logically missing cells occur. (Author/SV)

Analyzes advantages and disadvantages of methods of selecting sample sizes in multiple regression. Discusses importance of cross-validity to prediction studies. Describes categories of sample size selection methods: cross-validation approaches, rules of thumb, and statistical power methods. Uses multiple examples to present the precision power…

Regression analysis of 40 years of data on median income, education, divorce rate, and female-headed households was conducted to determine their influence on crime rates, especially homicide. Educational attainment had a significant bearing on criminality. Single parenting was less significant than low income. (SK)

A Monte Carlo study was conducted to examine the performance of several strategies for estimating the squared cross-validity coefficient of a sample regression equation in the context of best subset regression. Results concerning sample size effects and the validity of estimates are discussed. (TJH)

Distinguishes between multiple correlation and multiple regression analysis. Illustrates suggested information reporting methods and reviews the use of regression methods when dealing with problems of missing data. (SK)

Husbands' beliefs regarding justifying wife beating, holding violent husbands responsible for their behavior, and blaming battered wives for violence against them are investigated among Palestinian men. Patriarchal ideology provides a conceptual framework for presentation and discussion of the findings from multiple regression analyses.…

Depression in women with rheumatoid arthritis (RA) may be related to social role experiences, physical health, and age. The purpose of this study was to examine the social and health factors contributing to depression in two age groups of women with RA. One-hundred and thirty-eight midlife and late-life women with a diagnosis of RA participated in…

A high correlation has been found between domestic violence and stalking. However, very few studies have examined what factors predict the occurrence of stalking in relationships characterized by domestic violence. Using in-depth interviews with victims of domestic violence whose cases have gone through the criminal justice system, this article…

Attrition from the sciences remains a national problem. The authors present results from a survey of over 2,100 undergraduates that, contrary to previous research, suggests that teaching assistants (TAs) influence student retention in the sciences in multiple ways. Multiple linear regression (MLR) and student comments suggest that TAs influence…

The purpose of this study was to develop an age-generalized regression model to predict maximal oxygen uptake (VO sub 2 max) based on a maximal treadmill graded exercise test (GXT; George, 1996). Participants (N = 100), ages 18-65 years, reached a maximal level of exertion (mean plus or minus standard deviation [SD]; maximal heart rate [HR sub…

The purpose of this study was to investigate the relationship between the cognitive style and teaching style preferences of instructors enrolled in the Reserve Officer Training Corps instructor course at the Academic Instructor School at Maxwell Air Force base. Sixty-five cases were examined for two research questions: (1) To what extent is there…

While the physical correlates of knee osteoarthritis are well documented, less well documented are aspects of psychological functioning that may affect overall health and functional status. This paper describes the findings of a cross-sectional analysis that examined the strength of the relationship between selected psychological factors and the…

This study extended the work of S. Siddiqui, R. F. West, and K. E. Stanovich (1998), who studied the link between general print exposure and syllogistic reasoning. It was hypothesized that exposure to certain text structures that contain well-delineated logical forms, such as popularized scientific texts, would be a better predictor of deductive…

This study examined the correspondence between parent and adolescent reports of the adolescent's substance use in a population of parents concerned about, and experiencing problems resulting from, their teen's substance use. Seventy-five parents and their adolescents (76% not in treatment; 24% in treatment) were interviewed separately regarding…

The idea of "information commitments" refers to both learners' online searching strategies and the evaluative standards that students use to assess the accuracy and usefulness of information in web-based learning environments. Based upon the results of a pioneering and qualitative study on information commitments, this study aimed to develop an…
