Proc hpclus (B stands for what?)

Hello all,

I'm using "hpclus" process for clustering but I don't know "B", in this process, stands for what? And how should I set this value? I could just find that this number represents the number of Monte Carlo draws but I don't which value of this parameter is the best one for my analysis. I put part of my code here:

proc hpclus
data=ios
maxclusters=8
maxiter=100
seed=54321
NOC=ABC(B=25 minclusters=3 align=PCA);
score out=outscore;
input Dos Execute_Code Overflow Obtain_Information Gain_Previledges Bypass_a_Restriction Directory_Traversal Cross_Site_Scripting CSRF Memory_Curruption;
id cve_id;
ods output ABCStats=ABC;
run;

Thank you!

Yazdan

First stop is the docs.

B=number
specifies the number of reference data sets to be created for each cluster candidate. By default, B=1.

http://documentation.sas.com/?docsetId=emhpprcref&docsetVersion=14.2&docsetTarget=emhpprcref_hpclus_syntax01.htm&locale=en#emhpprcref.hpclus.proc_noc

It explains more in the links in the documentation.
