Ordinary least squares regression for examining individual growth trajectories. Produces plots that can be used for both informative and diagnostic purposes.


Provides tools for organizing, calculating, and plotting ordinary least squares growth curve trajectories. These type of models are typically used to diagnose the effectiveness of a specified time functional form at the individual level rather than at the group level (where FIML estimation is required).
