Hello Pniel,
I see that this post is from a while ago, so you might have figured out an answer to your question already. If not, this script might help with what you're trying to do.
dt = open( "$SAMPLE_DATA/Cytometry.jmp" );
mv = Multivariate( Y( :ForSc, :SideSc, :CD3, :CD8, :CD4, :MCB ) );
mv << Jackknife Distances( 1, Save Jackknife Distances );
jd = dt:Jackknife Distances << get values;
Regards,
Michael
