Describes problems of assessing change with short time-series data: unreliability of visual inference and fact that current statistical procedures cannot control Type I error because they underestimate positive autocorrelation. Shows how problems can be solved with new interrupted time-series analysis procedure (ITSACORR) that uses more accurate…

Introduces statistical methods for evaluating differences in patterns of time to response between two subject groups to determine better therapy. Uses data from hypothetical clinical trial to illustrate two elementary methods for analyzing survival data. Discusses generalization of methods to incorporate covariates. Concludes with general…

Notes that family researchers are increasingly using panel data to investigate family processes. To aid family researchers in understanding panel analysis, focuses on two panel analysis strategies--structural equation model techniques and methods of event history analysis. Several additional methods of analyzing panel data are also briefly…

Presents strategy for analyzing interdyadic differences in sequential data on social interactions. Shows how to statistically describe interactional structure within each dyad governing stream of that dyad's social interactive behavior and how scores describing dyadic structures can be related to covariate information about dyads. (Author/NB)

Asserts that, despite its growing popularity, there still exists confusion about the nature and proper use of logistic regression in family studies. Presents nontechnical discussion of logistic regression, with illustrations and comparisons to better-known procedures. Concludes that logistic regression can be powerful statistical procedure when…

Briefly describes core ideas behind LISREL (linear structural relationship) approach for studying structural models. Addresses some common issues with which family investigators deal, focusing on problems that researchers often face; questions they raise; and decisions they need to make in the process of model specification, estimation,…

Discusses current practices for statistical assessments of employment discrimination and suggests nonstatistical techniques that can be used to aid in interpreting results of statistical analyses. The techniques incorporate principles of Boolean algebra and allow holistic comparison of categories of similarly situated individuals. (CMG)

Reviews application of causal modeling in family research. Discusses uses of and critics' views of causal modeling to explain reasons for controversial position of causal modeling in social sciences. Reviews requirements for effectively implementing causal modeling strategy, commenting on some attempts of family researchers to use it. Includes…

Explains multiple regression, demonstrates its flexibility for analyzing data from various designs, and discusses interpretation of results from multiple regression analysis. Presents regression equations for single independent variable and for two or more independent variables, followed by a discussion of coefficients related to these. Compares…

Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)

Examines the comparative labor market experience of youth in the United States and eight other developed countries from 1960-1979, focusing upon unemployment levels and rates. Finds that the situation worsened in industrialized nations after the 1974-75 recession and that Japanese and German youth continue to have the most favorable job prospects.…

To establish a sophisticated planning mechanism that will translate readily to affordable tactical steps, university planners must have a good understanding of the cost structure of individual academic and administrative departments and of the efficiency and effectiveness of the staffs of those departments.
