Abstract: Methods and apparatus for crediting media exposure are disclosed. An example method includes deriving a plurality of travel paths traversed by respective ones of a plurality of respondents, determining, via a first technique, exposures of the respective ones of the plurality of respondents to a plurality of media sites based on the derived plurality of travel paths, and modifying the determined exposures to the plurality of media sites to improve a statistical accuracy of the modified determined exposures by constraining the determined exposures based on exposure information for the plurality of media sites obtained via a second technique different than the first technique.

Abstract: Methods, systems, and computer program products for implementing product randomization and analysis in a manufacturing environment are provided. A method includes processing products for a plurality of lots, at process equipment, using a randomization technique for selecting each product in the lots. The method further including generating an operation identification record for each operation in the process recipe that includes mapping, for each operation, a slot identifier associated with a randomly selected product to a process variable identifier, a process tool, and the operation. The method also includes defining slot groupings using slot identifiers for a product carrier and identifying product yield patterns by analyzing historical yields for each of the slot groupings.
