Abstract
Example methods and apparatus to replicate panelists using a local minimum solution of an integer least squares problem are disclosed. An example apparatus includes a data organizer to determine, by executing an instruction with a processor, estimated aggregate panelist data based on attribute data corresponding to a seed panel and weight estimates used to replicate respective seed panelists in the seed panel; and a weight determiner to iteratively adjust, by executing an instruction with the processor, the weight estimates based on comparisons of the estimated aggregate panelist data as determined based on the adjusted weight estimates and input aggregate panelist data to generate final weight estimates; and replicate, by executing an instruction with the processor, respective ones of the seed panelists based on final weight estimates to generate a synthetic audience representative of return path data reported by a plurality of media devices.
