1. One or more computer-readable media having computer-useable instructions embodied thereon to perform a method for aggregating curves, said method comprising: identifying a first curve and a second curve, wherein said first curve is represented by a first set of input values associated with a first set of output values, and wherein said second curve is represented by a second set of input values associated with a second set of output values; producing a third set of output values by applying said second curve to at least a portion of said first set of output values; producing a third set of input values by determining a plurality of input values that yield at least a portion of said second set of input values when said first curve is applied to said plurality of input values; and generating an aggregated curve, wherein said aggregated curve is represented by at least a portion of said first set of input values associated with at least a portion of said third set of output values, and wherein said aggregated curve is further represented by at least a portion of said third set of input values associated with at least a portion of said second set of output values.
