Three way interaction plot using PROC MIXED or Microsoft excel

nqb5210 — Tue, 22 Jun 2021 17:11:06 GMT

Hello,

I am trying to create graphs in excel or SAS to plot three-way interaction effects (treatment*time*race) to help visualize the data. Does anyone have any recommendations or know of any helpful resources?

Thanks

Renee

See the examples and discussion at "Visualize a mixed model that has repeated measures or random coefficients."

You have to decide if you want to include the random coefficients (eq, intercepts) or not. Include the random intercepts by using the OUTPRED= option. Otherwise, use the OUTPREDM= option.

Depending on your data and number of subjects you can decide whether to overlay or panel the visualization. Your best choice might be a panel: use PROC SGPANEL to create a panel of plots where each panel is a treatment and shows the race*time interactions. (Or you can panel by race and show the treatment*time interactions.)
