Patent ID: 8051030

Claim:
A method for placing outbound calls to accounts during a campaign period, each account having account information, the method comprising: dividing the campaign into plural time periods; dividing a sample population of accounts having call results into the plural subpopulations based upon a characteristic of a variable of the sample population; analyzing the subpopulations to identify at least one subpopulation having an inadequate sample size; selectively combining the identified subpopulation with one or more contiguous of the other subpopulations so that all subpopulations remaining after the selectively combining have an adequate sample size; generating a model for each subpopulation remaining after the selectively combining, the model predicting call results for outbound calls; applying the account information to the models with a computer system to predict outbound call results for the accounts during the plural time periods; and placing outbound calls with a telephone dialer to the accounts based at least in part on the predicted outbound call results.
