The merits of double exponential smoothing are discussed relative to other types of pattern-based enrollment forecasting methods. The difficulties associated with selecting an appropriate weight factor are discussed, and their potential effects on prediction results are illustrated. Two methods for objectively selecting the "best" weight…

New ways of using factor analysis in research designs are suggested in this paper that would allow research to move in new directions that are being suggested for educational technology. A brief simplified overview of factor-analytic techniques is given, followed by a description of some recent developments in factor-analytic techniques which make…

Four computer programs using the general purpose multiple linear regression program have been developed. Setwise regression analysis is a stepwise procedure for sets of variables; there will be as many steps as there are sets. Covarmlt allows a solution to the analysis of covariance design with multiple covariates. A third program has three…

The purpose of this study was to evaluate both the written Department of Motor Vehicles (DMV) driver licensing test, and a large sample of driver knowledge test items selected from the University of Michigan's Highway Safety Research Institute (HSRI) item pool. Test forms were administered to 48,000 California drivers license applicants. The…

The method used to arrive at four measures (three aptitude test scores and a high school grade point average) for predicting probable success is described. These measures were developed into three separate equations to predict success in: learning shorthand theory, reading shorthand notes, and dictation/transcription ability. (Author/MS)

The construction and interpretation of confidence intervals for the prediction of new cases in multiple regression analysis is explained. An example is provided. (JKS)

It is hypothesized that three factors would predispose women in specifiable positions to lower-than-expected salaries: length of service, rank, and proportion of females in the field. A multiple regression technique is used. (LBH)

A meta-analytic method synthesized results of 108 studies of the relationship between college grades and various criteria of adult achievement or success. Results showed little correlation, although effects were larger for military settings and studies before 1950. The predictive value of grades is questioned. (MSE)

An empirical study of statistical overkill investigated the generalizability of multiple regression equations as a function of the subject/variable ratio. Data from various-sized groups of rehabilitation clients were used to develop the equations. Findings showed that equations developed on samples with less than a 10 to 1 ratio failed to…

Paper reviews the test for regression lines and provides equations for expanding this test to regression planes. (Author)

Examined characteristics of the neighborhoods from which clientele of an alcohol treatment center were derived. Using 1970 Milwaukee census figures and patient information, computer analysis showed positive correlations between admissions and ethnicity, educational status, nonfamiy dimension, adult male and adolescent female neighborhoods,…

Appropriate methods are described for research workers in sociology to use as they perform causal analyses of data from surveys. Particular emphasis is placed on the causal analysis of qualitative variables. (Author/DB)

The use of life history or biographical information to predict various college experiences of women was examined in this study of 327 women. The results indicated that life history data could be used to make longitudinal predictions and are discussed in terms of their implications for counseling students in higher education. (Author/LBH)

A study demonstrated the use of logistic regression in conjunction with a new structural equations modeling technique for a university attrition study. The results and their methodological implications are discussed. (MSE)
