Case Study in Audit Selection
Build models to predict different outcomes. Positive Adjustment (Y/N). DPH Return (Group Membership). Actual $$ Adjustment.
Historical Cases selected for model build Cases with Prior audit – prior audit and organizational data. All Cases – organizational data only.
Deployment For each outcome combine predictions for those with and
without previous audit data . For each outcome predict using organizational data only.
