Analyzing developmental trajectories: A semiparametric, group-based approach
- D. Nagin
- 1 June 1999
Agroup-based method for identifying distinctive groups of individual trajectories within the population and for profiling the characteristics of group members is demonstrated.
A SAS Procedure Based on Mixture Models for Estimating Developmental Trajectories
This article introduces a new SAS procedure written by the authors that analyzes longitudinal data (developmental trajectories) by fitting a mixture model. The TRAJ procedure fits semiparametric…
Developmental trajectories of childhood disruptive behaviors and adolescent delinquency: a six-site, cross-national study.
The results indicate that among boys there is continuity in problem behavior from childhood to adolescence and that such continuity is especially acute when early problem behavior takes the form of physical aggression.
Group-based trajectory modeling in clinical research.
The challenges associated with the application of both group-based trajectory and growth mixture modeling are discussed, and a set of preliminary guidelines for applied researchers to follow when reporting model results are proposed.
Trajectories of boys' physical aggression, opposition, and hyperactivity on the path to physically violent and nonviolent juvenile delinquency.
A semi-parametric mixture model was used with a sample of 1,037 boys assessed repeatedly from 6 to 15 years of age to approximate a continuous distribution of developmental trajectories for three…
Criminal Deterrence Research at the Outset of the Twenty-First Century

- 1 January 1998
Evidence for a substantial deterrent effect is much firmer than it was two decades ago. However, large gaps in knowledge on the links between policy actions and behavior make it difficult to assess…
Advances in Group-Based Trajectory Modeling and an SAS Procedure for Estimating Them
Extensions of the methodology and of the SAS procedure that have been developed since Jones et al. (2001) are summarized to illustrate how group-based trajectory modeling lends itself to presentation of findings in the form of easily understood graphical and tabular data summaries.
Enduring individual differences and rational choice theories of crime
In explaining crime, some criminological theories emphasize time-stable individual differences in propensity to offend while others emphasize more proximate and situational factors. Using scenario…
Imprisonment and Reoffending
Imprisonment is the most severe punishment in democratic societies except for capital punishment, which is used only in the United States. Crime prevention is its primary rationale. Imprisonment may…
