Scoring new data from random forest node

How to score a new data from the random forest node in EM. Also how to account for decision node?

Where is the data you are trying to score?

If it's in a database, see this tip: https://communities.sas.com/t5/SAS-Communities-Library/Tip-How-Can-I-Apply-HP-Forest-Score-Code-to-Distributed-Data/ta-p/221493

If the data is in a SAS data set and your flow doesn't contain score code from any other nodes, you can do the following in a SAS Code node, SAS session, or SAS Enterprise Guide for the flow IDS -> HP Forest -> Score:

%let hpfst_score_input = sampsio.dmagecr;
%let em_score_output = work.myscoredata;

< paste the code from the Score node >

run;

hpfst_score_input = is the data set that you want to score
em_score_output = is the data set that you want to create (WORK. is only for example)
be sure to add a RUN; at the end - not having it gives an error.

Does the scoring code, takes care of decision node preference, automatically?
