A method to provide estimates of parameters of specified nonlinear equations from ordinal data generated from a crossed design is presented. The statistical basis for the method, called NOPE (nonmetric parameter estimation), as well as examples using artifical data, are presented. (Author/JKS)

Repeated measures designs often involve dichotomization of a continuous variable in order to be amenable to the analysis of variance nature of such designs. An alternative to that approach wherein the independent variable is kept continuous is presented. (JKS)

There are a variety of formulas for reducing the positive bias which occurs in estimating R squared in multiple regression or correlation equations. Five different formulas are evaluated in a Monte Carlo study, and recommendations are made. (JKS)

Factor scale scores are sometimes used as weights to create composite variables representing the variables included in a factor analysis. If these composite variables are then used to predict some dependent variable, serious theoretical and methodological problems arise. This paper explores these problems and suggests strategies for circumventing…

Tried to determine reliability and validity of an adapted vocational indecision scale designed for undergraduates. Findings suggest that characteristics of the adapted indecision scale for the graduate students sample are similar to the characteristics of the unadapted instrument for the undergraduate sample.

Variables used in applicant selection into the British Civil Service were analyzed for a sample using varimax factor analysis, multidimensional scaling and multiple regression. Results indicated that four dimensions or factors of applicant selection were consistent across a variety of settings and analyses. (JKS)

A multiple regression analysis of sequential effects in magnitude estimation and absolute identification is presented as an alternative to the approach used by Lockhead and his students. The new analysis indicates that sequential effects do not extend over more than one trial. (Editor)

Low income families were interviewed to determine the factors related to the number of family food servings per week. More food servings were found to be associated with participation in WIC, household size, and the number of different income sources. The number of food servings decreased the last week of the month, particularly in families with…

Points out reasons for using graphical methods to teach simple and multiple regression analysis. Argues that a graphically oriented approach has considerable pedagogic advantages in the exposition of simple and multiple regression. Shows that graphical methods may play a central role in the process of building regression models. (Author/LS)

A multiple regression model for estimating true change of an individual by using information in addition to pretest-posttest data is described. Longitudinal panel or multi-wave data taken between the pretest and the posttest constitute the additional information. (TJH)

Although the decennial census provides poverty figures for states and other subnational geographic units, their utility declines over the course of a decade, causing interest in producing postcensus estimates for a variety of indicators. This study extends recent efforts to estimate postcensus poverty figures for states using multiple regression…

This study found a significant relationship between the Kaufman Brief Intelligence Test (K-BIT) and the Wechsler Intelligence Scale for Children-III (WISC-III) in 63 youth at a psychiatric hospital. A multiple regression equation was derived to provide an estimate of the WISC-III Full Scale Intelligence Quotient using the composites of the K-BIT.…

Evaluates 3 1985-87 mass media campaigns designed to prevent smoking by adolescents, using data gathered by telephone contact with over 2,000 households. The campaigns had but a modest or indeterminate result. Radio proved as effective as television. (DM)

Applies an extension of an earlier multiple regression model for twin analysis to the problem of detecting linkage in a quantitative trait. Detects a number of possible linkages, indicating that the approach is effective. Discusses detecting genotype-environment interaction and the issue of power. (RS)

Sexual attitudes and their influence on sexual behavior among high school students (N=1,587) and parents (N=1,372) were investigated. Multiple regression analyses yielded models for attitudes about premarital sexual intercourse with separate models for adolescent females and males. When family factors were integrated, the model had more…
