customize plot of predicted values from PROC GENMOD

Hi,

I am running a GEE in proc genmod and would like to customize the plot that it can automatically produce using the 'effectplot' statement. I am running a model that has two continuous predictor and I would like to plot the interaction at 1 SD above and below the mean for the moderating variable, which in my case are at the values -.76 and +.76. The syntax I am using below will produce the plot I want, but I would like to edit the font, x axis limits, etc.

proc genmod data=data;
class idx;
model y = x z x*z / dist=nb;
repeated subject=idx / type=ind covb corrw;
EFFECTPLOT slicefit (x = x sliceby = z = -.76 .76 ) / CLM;
run;

Thanks for the advice!

You have two options, one is to save the graphics to a file and edit it with Designer tool. This is somewhat manual, somewhat automated.

A second is to pipe the data set to a data file and then recreate the plot using SGPLOT which allows you to customize everything you desire.

Thanks, Reeza. I'll check out the first option. And for the second, to be clear you mean piping the *predicted* values dataset into a data file and then create the plot using SGPLOT?

The data used to create the EFFECTPLOT itself can be piped to a data set so you don't have to do additional calculations or restructuring of the data set and then using SGPLOT on that data set. It should save you at least a few steps with that approach. If this needs to be repeated at all this is the better option though ODS Graphics Designer does have some automation capabilities.
