Methods and apparatus to calibrate media ratings based on return path data are disclosed. An apparatus includes programmable circuitry to execute machine readable instructions to: determine a subscriber calibration factor for media based on first panel tuning information obtained from first metering devices in first panelist households that subscribe to a content provider that provides media through return path data (RPD) devices; determine a nonsubscriber calibration factor for the media based on second panel tuning information obtained from second metering devices in second panelist households that do not subscribe to the content provider; and determine a final rating for the media based on an initial rating and at least one of the subscriber calibration factor or the nonsubscriber calibration factor, the initial rating based on RPD tuning information obtained from RPD devices in subscriber households that subscribe to the content provider.

Methods and apparatus to calibrate audience measurement ratings based on return path data

An example apparatus disclosed herein includes at least one memory, instructions, and at least one processor to execute the instructions to: receive first HyperLogLog (HLL) data from a first server of a first database proprietor and second HyperLogLog (HLL) data from a second server of a second database proprietor, the first HLL data including obfuscated first user impression data and the second HLL data including obfuscated second user impression data; generate union HLL data based on the first HLL data from the first database proprietor and the second HLL data from the second database proprietor by performing a union of data sets of the obfuscated first user impression data represented in the first HLL data and the obfuscated second user impression data represented in the second HLL data; and determine a total number of deduplicated unique audience members based on the union HLL data generated by the vector analyzer.

Methods and apparatus to determine a unique audience for internet-based media

Methods, apparatus, systems and articles of manufacture are disclosed to generate measures of unique audiences for Internet-based media. An example apparatus disclosed herein includes at least one memory, instructions, and at least one processor. The processor to execute the instructions to: receive first HyperLogLog (HLL) data from a first server of a first database proprietor and second HyperLogLog (HLL) data from a second server of a second database proprietor, the first HLL data including obfuscated first user impression data and the second HLL data including obfuscated second user impression data; generate union HLL data based on the first HLL data from the first database proprietor and the second HLL data from the second database proprietor by performing a union of data sets of the obfuscated first user impression data represented in the first HLL data and the obfuscated second user impression data represented in the second HLL data; and determine a total number of deduplicated unique audience members based on the union HLL data generated by the vector analyzer.

Methods and apparatus to calibrate media ratings based on return path data are disclosed. An apparatus includes a processor and memory including instructions that, when executed, cause the processor to: determine an initial rating for the media provided in a first geographic area based on return path data (RPD) tuning information obtained from RPD devices in subscriber households in the first geographic area; determine a first panelist rating for the media provided in a second geographic area based on first panel tuning information obtained from first metering devices in a first subset of panelist households in the second geographic area; determine a nonsubscriber calibration factor based on the first panelist rating; and determine a final rating for the media in the first geographic area by modifying the initial rating based on the nonsubscriber calibration factor.

Methods, apparatus, systems and articles of manufacture are disclosed to generate measures of unique audiences for Internet-based media. An example method disclosed herein includes a salt generator to generate a shared salt at a first database proprietor, a database proprietor interface to the shared salt to a second database proprietor, a Hyperloglog (HLL) generator to generate a first hash vector at the first database proprietor based on the shared salt and first user impression data associated with media, the first hash vector to obfuscate first personally identifiable information of first subscribers of the first database proprietor and an AME interface to send the first hash vector to a database containing a second hash vector, the second hash vector generated by the second database proprietor using second user impression data and the shared salt, the second hash vector to obfuscate second personally identifiable information of second subscribers of the second database proprietor, the first hash vector and the second hash vector to enable a third party to a deduplicate audience size corresponding to the first user impression data and the second user impression data.

Methods and apparatus to calibrate media ratings based on return path data are disclosed. An apparatus includes a ratings calculator to calculate an initial local rating for media provided in a first geographic area based on local return path data (RPD) tuning information obtained from local RPD devices in subscriber households in the first geographic area. The subscriber households subscribe to a content provider that provides the media through the local RPD devices. The apparatus further includes a calibration factor calculator to calculate a nonsubscriber calibration factor based on a first panelist rating for the media corresponding to a first subset of panelist households that do not subscribe to the content provider. The ratings calculator modifies the initial local rating based on the nonsubscriber calibration factor to calculate a final local rating for the media in the first geographic area.
