Homicidality rates have been shown to be more prominent among persons diagnosed with mental disorders as compared to the general population. However, the role that anxiety plays in homicidal ideation and intent is poorly understood. This study investigated predictors of homicidal intent, thought, or plan in an adult population of psychiatric…

A study to present specific hypothesis that satisfactorily explain the boiling point of a number of molecules, CH[subscript w]F[subscript x]Cl[subscript y]Br[subscript z] having similar structure, and then analyze the model with the help of multiple linear regression (MLR), a data analysis tool. The MLR analysis was useful in selecting the…

Two samples of Slovak women in higher education were surveyed in order to determine the extent to which organizational commitment and life satisfaction are related to personal and work-related attributes. Organizational commitment was found to be related to the work-related attributes of role conflict and role ambiguity. These work-related…

The study investigated the interactive and relative effects of self-concept, self-efficacy and ICT literacy level on students' motivation towards the use of digital technology. The study sample comprised 1216 participants drawn from three universities in Ogun State, Nigeria. Four valid instruments were used in collecting data. Multiple regression…

This research sought to determine whether any measure(s) used in the Carnegie Foundation's classification of Doctoral/Research Universities contribute to a greater degree than other measures to final rank placement. Multilevel Modeling (MLM) was applied to all eight of the Carnegie Foundation's predictor measures using final rank…

Discussion is one form of active learning, which has been linked to better learner outcomes. Little is known about the relationship between active learning through discussion and learner outcome in the online environment. Here, we construct an index of active learning online that includes the number of postings a student has read, the number of…

The extent to which standardized regression coefficients (beta values) can be used to determine the importance of a variable in an equation was explored. The beta value and the part correlation coefficient--also called the semi-partial correlation coefficient and reported in squared form as the incremental "r squared"--were compared for…

The use of multiple regression in identifying students with learning disabilities was investigated with 281 ninth grade students. Five sets of predictor variables were chosen to predict grade point average in grade 9: verbal and nonverbal IQ, sex, socioeconomic status (SES), and grade point average in grade 7. Five groups of overachievers, normal…

The uses and restrictions of commonality analysis are described. Commonality analysis has been increasingly used as a method to examine the relative importance of independent variables, through the partitioning of variance among the variables of the regression equation into unique and common components. The effects of all other independent…

Multiple regression analysis is frequently being employed in experimental and non-experimental research. However, when data include predictor variables that are correlated, some regression results can become difficult to interpret. This paper presents a study to provide a demonstration that structure coefficients may be useful in these cases.…

This paper presents two major criticisms of the construct validity investigation of the McCarthy Scales of Children's Abilities conducted by Watkins and Wiebe (1980). The criticisms pertain to the nature of the data presented and the accuracy and appropriateness of the statistical procedures employed. (BS)

Using step-wise multiple regression analyses, regression equations were generated for sixty school age subjects with choice and stage of moral reasoning on moral dilemmas as the dependent variables. The implications of the findings for further research and curriculum were discussed. (Editor/RK)

Purpose of this investigation was to determine whether the inclusion of quadratic and/or interaction terms in a regression model would improve the prediction of student nurses' grade point averages. (Authors)

Virtually all parametric statistical procedures have been shown to be special cases of canonical correlation analysis. This article proposes a logic for conducting stepwise canonical correlation analyses, based upon evaluation of canonical communality coefficients. The procedure is a direct analogue of stepwise multiple regression. (Author/RD)
