Hi,
I've run a discriminant analysis for a binary category group & the code I used is the following:
proc discrim data=discrim;
class group;
var var1 var2 var3 var4 var5;
run;
Now, I want to plot the each groups discriminant scores across the 1st linear discriminant function. Can anybody please tell me the code to do it?
Regards,

You can use the following code to get linearDisdinctFunction ,then use proc gplot
ods output LinearDiscFunc=line; proc discrim data=sashelp.iris method=normal pool=yes; class Species; var PetalWidth; title2 ’Using Normal Density Estimates with Equal Variance’; run;

Not really certain what it is you are attempting to accomplish here but you might find this helpful:
ods output LinearDiscFunc=discrim_results;
proc discrim data=discrim;
class=group;
var var1-var5;
run;
Hi,
I R software, one can visualy examine how well the discriminant function demarcate the 2 groups. Please find the snap below. But in SAS I just can't able to do it. I was just looking for SAS code to get a plot like the one below.
