Jackknife Predicted Values

pniel — Thu, 24 Jan 2013 20:41:03 GMT

Dear developers.

I need to retrieve the predicted value from Jackknife

I saw an example of getting the value from the table in the scripting guide..

myJackVal = column(“Jackknife Distances”)<<Get Property(“Jackknife value”);

Unfortunately I don’t know how to save the values to the data table.

Can someone please help?

Thanks,

Pniel

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

Thanks for the helpful answer, Michael. With regard to Jackknife distances, in the graph I can see an UCL value being displayed as well as a horizontal dashed line marking the UCL value. When I tried to extract the UCL value I realized it is stored in a FrameBox. Is there any way to extract the UCL value through JSL?

If you save the Jackknife distancies, the column that is saved has a Column Property called Jackknife Value. You can retrieve that value with

UCL = col << get property( "Jackknife Value" )
