The Relationship of ANOVA Models with Random Effects and Repeated Measurement Designs.
Peer reviewed Peer reviewed
Schuster, Christof; von Eye, Alexander – Journal of Adolescent Research, 2001
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…

Sampling Schemes and the Selection of Log-Linear Models for Longitudinal Data.
Peer reviewed Peer reviewed
von Eye, Alexander; Schuster, Christof; Kreppner, Kurt – Journal of Adolescent Research, 2001
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…

Assessing the Impact of Exposure Time and Incapacitation on Longitudinal Trajectories of Criminal Offending.
Peer reviewed Peer reviewed
Piquero, Alex; Blumstein, Alfred; Brame, Robert; Haapanen, Rudy; Mulvey, Edward P.; Nagin, Daniel S. – Journal of Adolescent Research, 2001
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…
