Introduces the "person approach" to the study of adolescence, and discusses the consequences of the approach for theoretical thinking and research methodology. Reviews major types of pattern-based methods used for carrying out a person approach and discusses methodological challenges for adolescent research, including interindividual…

Discusses the effects of sampling scheme selection on the admissibility of log-linear models for multinomial and product multinomial sampling schemes for prospective and retrospective sampling. Notes that in multinomial sampling, marginal frequencies are not fixed, whereas for product multinomial sampling, uni- or multidimensional frequencies are…

Demonstrates how different experimental designs arise from variation of three basic distinctions: block versus treatment factors, fixed versus random factors, and crossed versus nested factors. Argues that understanding how these distinctions influence statistical analysis can reduce amount of experimental design. Presents an example of this by…

Examined effect of accounting for exposure (incarceration) time on arrest rate of 272 paroled serious offenders followed through age 33. Analysis without exposure time adjustments suggested that over 92 percent exhibited highest arrest activity in late teens and early 20s. Adjusted for exposure time, about 72 percent showed a decline in arrest…

Describes a random effects discrete time survival model that addresses problems of measurement error and sample design complexities. Demonstrates the effectiveness of the model in an analysis of retrospective report data on the age of onset of smoking from two cross-sectional school-based studies. (JPB)

Demonstrates how Rasch models can be used to study differences in item salience within and across time points, and that even if a test does not fulfill assumptions of the Rasch model, it can be used to obtain information on item functioning across participants and over time. Illustrates method using longitudinal data from Baltimore Prevention…
