"Clustering with Loops?"

Hi RM Masters!

I am a novice with RM and inexperienced with loops and macros. I need advice on how to structure a process to loop clustering. I am trying to get three centroids - a low / medium / high for each location and illness combination (see below). This will be used so when future data is received about how long a contract from [location B] for [pain] is taking I can tell whether it is taking too long, on track, or ahead of schedule.

I'm pretty sure I want  to run clustering (k-means) with looping for all unique combinations of the attributes Location and Illness. So I want to get 3 centriods for [Location A & Ebola] subset, three centroids for [Location B & Cold], [Location C & Cold], etc. The attributes Milestone 1, Milestone 2, Milestone Final are the numerical attributes I want to use for my clustering.

My data set is about 13,000 examples and I have some other polynomial attributes that aren't listed here.

Please forgive the formatting; here is a representative sample of the example set:

Contract ID   Location   Illness             Contract Status Contract Type     Begin Date           Milestone 1    Milestone 2   Milestone Final
1                       A   Ebola               Finished               Big               1/10/2013               78                 133                 154

13                     D                 Upset Stomach Finished             Small               11/27/2009         48               103               194
14                     D                   Ebola               Finished       Big               5/18/2005                 86               101               160
15                     D                Ebola                     Finished       Big               11/15/2009         7               148               164
16                     D                   Pain             Unfinished       Small               5/25/2005               29                    117               242
18                     D                 Club foot             Unfinished       Big               4/28/2011               41               147               190
19                     D                 Club foot             Unfinished       Small               4/20/2007               48               113               229

Also, any thoughts on how to learn to work with loops macros would be wonderful.

Thanks in advance for the advice!

    This might help.  First, use the Generate Concatenation operator to create a new field that concatenates Location and Illness.  Then, feed that into a Loop Values operator.  When you're in the Subprocess for the loop, you will want to filter based on your new concatenated attribute.  The trick being, you will want to use a %{loop_value} -- that is, Location_Illness=%{loop_value}.  Then, just continue from there.  Hope this helps.
