JSL help: Plot Bootstrap -feature imortance TOP 10 columns for graph builder

turkeyhazel

Dear powerful JMP user,

 

   I want to make an automation script using jsl to fulfill the function below:

  Use bootstrap method for my dataset analysis, then plot the top 10 feature importance parameter for view, could you pls share me an sample for how to do that?

 

Regards

Here is an example of one way to do this.  I am not sure if it is capturing the top 10 the way you envision, but it should give you an idea of how to proceed.

Names Default To Here( 1 );

// Open Data Table: semiconductor capability.jmp
// → Data Table( "semiconductor capability" )
dt = Open( "$SAMPLE_DATA/semiconductor capability.jmp" );
// For the example, Change column modeling type: wafer
Data Table( "semiconductor capability" ):wafer << Set Modeling Type( "Continuous" );

// Launch platform: Bootstrap Forest
bf = dt << Bootstrap Forest(
	Y( :wafer ),
	X(
