Latent Growth Curve Models with Proc Traj

I am using `proc traj` for latent growth curve model. My question is regarding the code provided ahead.

In this data set the outcome `helpless` is measured at three time points and so are the time-varying exposures like `life_satisfac`. We also have fixed exposures like `gender`. I am not sure how to incorporate both `life_satisfac` and `gender` in the code below:

PROC TRAJ DATA=h OUT=OF OUTPLOT=OP OUTSTAT=OS OUTEST=OE ITDETAIL;

ID subNbr; VAR Helpless1-Helpless3; INDEP life_satis1-life_satis3;

MODEL CNORM;Min 6; MAX 24; NGROUPS 3; ORDER 1 1 1;

RUN;



%trajplot (PlotFile=OP,StatFile=OS, “Title of graph”, “Subtitle”, “Y-axis label”, “X-axis label”);

Helpless is measured on a likert scale from 6-24; life_satisfac is also on a likert scale from 5-35.

Thank you for your response. I did get my code form the resource your provided.
