For example in a linear growth model, the fixed effect for the slope describes normative changes in terms of the average increase or decrease for the sample as a whole whereas the random effect indicates the amount of variability around that average trend. For example, if the same person is not found to update the study, the research cannot be carried out. Policy-makers are considering large-scale programs aimed at self-control to improve citizens’ health and wealth and reduce crime.
