the system and process used for modeling of data sets is improved by achieving one pass modeling which proactively anticipates issues with the model and deals with these issues prior to model formation . the anticipated issues include those involving offending variables , which are initially identified and eliminated so as to avoid any further contribution by those variables . once offending variables are eliminated , the process then deals with variables having only minimal contributions . to create a simplified and more effective model , these minimal contributors are then eliminated before completion of the model .
