OLS growth curve trajectories

Provides tools for more easily organizing and plotting individual ordinary least square (OLS) growth curve trajectories.

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).



  • mostely internal fixes, but some new plotting features added


  • standard error polygons added for subjplot function


  • major documentation additions, filling in the placeholders that were previously there.

  • removed .gitignore to avoid problems with Rstudio projects

  • moved changes to NEWS, since it is better tracked within the R HTML help guides
