The
dt << Select All Rows;
is a message that is only used in relationship to selecting all rows in a data table.
What you want to do, is to get all of the Quantile Outlier rows and select them. In your example
obj << Select Rows( :"Q-E"n, :"ZN-E"n );
tells JMP to select the Quantile Outliers found for the columns, Q-E and ZN-E.
What needs to be done to select all of the rows, is to specify all of the columns being analyzed in the Explore Outliers platform. In your case, that list of columns are all of the columns found in the Sensor Measurements group of columns. Therefore, to get all of the names of the columns in that group, one simply uses
theGroup = dt << get column group( "Sensor Measurements");
and then sends the Select Rows message to the platform
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Water Treatment.jmp" );
obj = dt <<
Explore Outliers(
Y( Column Group( "Sensor Measurements" ) )
);
obj << Quantile Range Outliers( Tail Quantile( 0.3 ) );
theGroup = dt << get column group( "Sensor Measurements");
obj << Select Rows( eval(theGroup));
