Methods and apparatus to generate electronic mobile measurement census data
An example apparatus includes at least one processor and first memory comprising computer readable instructions that, when executed, cause the at least one processor to log an impression in second memory at an audience measurement entity based on a communication received from a computing device. The example computer readable instructions, when executed, cause the at least one processor to determine that a primary user of the computing device is not the user operating the computing device when a first probability score for the primary user does not satisfy a threshold, and in response to determining that the primary user is not the user operating the computing device, identify one of a plurality of secondary users as the user operating the computing device. The example computer readable instructions, when executed, cause the at least one processor to store demographic information of the user operating the computing device.

in response to determining that the primary user is not the user operating the client device, determine the user operating the client device is one of a plurality of secondary users by:
determining probability scores for corresponding ones of the secondary users, the secondary users being household members residing in the household with the primary user, the probability scores indicative of probabilities that corresponding ones of the secondary users are the user operating the client device; and
identifying the one of the secondary users as corresponding to a highest probability score as being the user operating the client device; and
means for processing to:
reduce a misattribution error by associating demographic information of the user operating the client device with the logged impression associated with the media.
2. The apparatus of claim 1 , wherein when a size of the household equals one, the means for correcting impressions is to identify the primary user as the user operating the client device.

4. The apparatus of claim 1 , wherein the threshold is a calibration factor divided by a size of the household.
5. The apparatus of claim 1 , wherein the means for processing is to reduce required processing resources on the client device when associating the demographic information of the user operating the client device with the logged impression by identifying the user operating the client device without requiring the user operating the client device to self-identify.
6. The apparatus as defined in claim 4 , wherein the calibration factor is based on demographic information of the primary user and a type of the client device.
7. The apparatus as defined in claim 6 , wherein the demographic information of the primary user and the type of the client device define a first demographic group, and the calibration factor is a ratio of an average time that the first demographic group accessed the media and an average time that all demographic groups accessed the media.
8. An apparatus to correct media measurement data generated by a server, comprising:
means for generating electronic mobile measurement data based on network communications received from client devices, the network communications corresponding to media accessed at the client devices;
means for generating an assignment model to:
select attributes associated with the electronic mobile measurement data to include in the assignment model;
generate the assignment model based on the attributes and a first portion of the electronic mobile measurement data; and
determine a percentage of a second portion of the electronic mobile measurement data that the assignment model correctly associates with corresponding users of the client devices; and
means for correcting impressions to, when the percentage satisfies a threshold:
determine: (a) when a user operating a client device is a primary user based on the assignment model, and (b) when the user operating the client device is one of a plurality of secondary users based on the assignment model; and
associate demographic information of the user with the electronic mobile measurement data to reduce a misattribution error generated by the means for generating the electronic mobile measurement data when generating the electronic mobile measurement data.
9. The apparatus of claim 8 , wherein the means for correcting impressions is to associate the demographic information of the user operating the client device with the electronic mobile measurement data to reduce processing resources on the client device by identifying the user operating the client device without requiring the user operating the client device to self-identify.
10. The apparatus of claim 8 , wherein the attributes are first attributes and the assignment model is a first assignment model, and when the percentage does not satisfy the threshold:
the means for generating the assignment model is to:
select second attributes associated with the electronic mobile measurement data; and
generate a second assignment model based on the second attributes and the first portion of the electronic mobile measurement data; and
the means for correcting impressions is to:
identify the user operating the client device as at least one of the primary user or one of the plurality of secondary users based on the second assignment model; and
associate the demographic information of the user with the electronic mobile measurement data to reduce the misattribution error.
11. The apparatus of claim 8 , wherein the attributes include at least one of demographic information, household information, media information, or information related to the client devices.
12. The apparatus of claim 8 , wherein the threshold is based on at least one of an error tolerance of a customer of an audience measurement entity or a known amount of error in the first portion of the electronic mobile measurement data.
13. The apparatus of claim 8 , wherein when a size of a household of the user operating the client device equals one, the means for correcting impressions is to identify the primary user as the user operating the client device.
14. An apparatus for generating electronic media measurement census data, comprising:
at least one processor; and
first memory comprising computer readable instructions that, when executed, cause the at least one processor to:
log an impression in second memory at an audience measurement entity based on a communication received from a computing device, the logged impression corresponding to media accessed at the computing device by a user operating the computing device;
determine that a primary user of the computing device is not the user operating the computing device when a first probability score for the primary user does not satisfy a threshold, the first probability score indicative of a probability that the primary user is an audience member of the media accessed at the computing device, the primary user being a household member of a household; and
in response to determining that the primary user is not the user operating the computing device, identify one of a plurality of secondary users as the user operating the computing device by:
determining probability scores for corresponding ones of the secondary users, the secondary users being household members residing in the household with the primary user, the probability scores indicative of probabilities that corresponding ones of the secondary users are the user operating the computing device; and
identifying the one of the plurality of secondary users corresponding to a highest probability score as being the user operating the computing device; and
