The paper provides an overview of discriminant analysis and illustrates how this technique can maximize the effectiveness and efficiency of procedures for identifying intellectually gifted students. (Author/CL)

The project evaluated the discriminant validity of gifted intermediate children's (N=97) divergent thinking test scores with multitrait-multimethod and factor analytic procedures. Results indicated that the indices drawn from the divergent thinking tests lacked discriminant validity in this gifted sample. (Author/CL)

Evaluated the hypothesis that a response set accounts for relationships between obvious or subtle statements and criteria by assessing the discriminant validity of two Minnesota Multiphasic Personality Inventory (MMPI) scales subdivided on the obvious-subtle dimension. The full scales appear to possess more discriminant validity than their obvious…

The purpose of this paper is to assist researchers, practitioners, and graduate students in identifying and addressing key questions related to the task of choosing among the analytic techniques designed to analyze a dichotomized dependent variable with a set of independent variables. The discussion is limited to (1) the analysis of data by the…

In an attempt to further substantiate Bender's throry of maturational lag as a factor in schizophrenia, 72 schizophrenic children, ages 7 to 15 were tested on their ability to make right-left discriminations. The results indicated that the schizophrenic children as a group performed substantially poorer than normal children. (CS)

Examples are given of problems that have solutions or discriminants'' similar to that of the quadratic formula; theorems pertaining to these problems are stated and proved. (DT)

If the null hypothesis of a one-sample test of multivariate means is rejected, the dimension of the line joining the population centroid and the hypothesized centroid can be interpreted with a linear function, using a discriminant function and the correlation of each dependent variable with a discriminant score. (Author/BW)

Fisher's two-group discriminant function has been generalized in two different ways for the case of three or more groups, leading to confusion in the literature. The precise functional relation between the two functions is derived, and the interpretation of the two functions is discussed. An example is provided. (Author/CTM)

Recent trends in the analysis of categorical or nominal variables were discussed for univariate, multivariate, and psychometric problems. It was shown that several statistical procedures commonly used with these problems have analogues which can be applied to assessing categorical variables. (Author/CTM)

Methodological issues raised in a feasibility study to develop a psychological test to predict illicit drug use are described. A small set of items was found to be related to prior drug use. These items maintained their ability to discriminate users and non-users in a cross-validation study. (Author/JKS)

Predictive discriminant analysis and descriptive discriminant analysis are described, and the use of three popular statistical packages to obtain computational results for each type of discriminant analysis is reviewed. Results from two Biomedical Computer Program (BMDP), four Statistical Analysis System, and two Statistical Package for the Social…
