Patent ID: 8086640

Claim:
A method for modifying data coverage in a modeling computer system, comprising: obtaining data records relating to a plurality of input variables and one or more output parameters; selecting a plurality of input parameters from the plurality of input variables; evaluating, by a processor of the modeling computer system, a coverage of the data records in a modeling space by determining a data density of the data records in the modeling space, the evaluating including: dividing the modeling space into a plurality of hyper-quadrants; calculating a data density for each hyper-quadrant based on a number of data records in the respective hyper-quadrant; generating a histogram based on the calculated data densities of each hyper-quadrant; and determining a statistical difference in a data density distribution between the hyper-quadrants based on the generated histogram; detecting a data coverage condition based on whether the determined statistical difference exceeds a first threshold; and when a data coverage condition is detected: modifying the coverage of the data records; and generating a computational model indicative of interrelationships between the plurality of input parameters and the one or more output parameters based on the modified data records.
