Methods, apparatus, systems and articles of manufacture to assign viewers to media meter data are disclosed. An apparatus includes processor circuitry to execute computer readable instructions to at least: identify a candidate household from a plurality of second households to associate with a first household based on an analysis of a first duration of time first media was presented by a first media presentation device and a second duration of time second media was presented by second media presentation devices; match different ones of first panelists of the first household with matching ones of second panelists of the candidate household; and impute respective portions of the first duration of time to the different ones of the first panelists based on portions of the second duration of time for which the matching ones of the second panelists of the candidate household were exposed to the second media.

Methods and apparatus to assign viewers to media meter data

Methods, apparatus, systems and articles of manufacture to assign viewers to media meter data are disclosed. An apparatus includes memory, and a processor to execute instructions to: determine first probabilities for first panelists in a first household based on a first number of minutes of first media presented by a first media presentation device monitored by a first meter, determine second probabilities for second panelists in a plurality of second households based on a second number of minutes of second media presented by second media presentation devices monitored by a plurality of second meters, compare the first probabilities and the second probabilities to identify a candidate household from the plurality of second households to associated with the first household, and impute respective portions of the first number of minutes to corresponding ones of the first panelists when monitored behavior of the candidate household matches monitored behavior of the first household.

Methods, apparatus, systems and articles of manufacture to assign viewers to media meter data are disclosed. An apparatus includes memory to store instructions, and a processor to execute the instructions to at least: determine first probabilities for first panelists in a media meter household during a first set of time periods, determine second probabilities for second panelists in a plurality of learning households during a second set of time periods, compare the first probabilities and the second probabilities to identify a candidate household from the plurality of learning households to associated with the media meter household, and impute ones of the first number of minutes to individual ones of the first panelists when second panelist behavior data associated with the candidate household indicates activity during one of the second set of time periods that matches activity in the media meter household during one of the first set of time periods.

Methods, apparatus, systems and articles of manufacture are disclosed to assign viewers to media meter data. An example method includes calculating, with a processor, first viewing probabilities for tuning panelists in a tuning household during a first set of time periods, calculating, with the processor, second viewing probabilities for viewing panelists in a plurality of candidate viewing households during a second set of time periods, identifying, with the processor, a matching one of the plurality of candidate viewing households based on an absolute difference value between an average value of the first viewing probabilities and respective ones of average values of the second viewing probabilities, and reducing an imputation error by imputing, with the processor, tuning minutes of the tuning household as viewing minutes for the respective tuning panelists when the matching one of the plurality of candidate viewing households exhibits viewing activity during one of the second set of time periods that matches one of the first set of time periods.

Methods and apparatus to assign demographic information to panelists are disclosed. Example disclosed methods include generating decoy database proprietor identifiers based on probability density functions. The example method also include querying a database proprietor using panelist database proprietor identifiers and the decoy database proprietor identifiers to obtain demographic information associated with the panelist database proprietor identifiers. The example method also include assigning the panelist database proprietor identifiers to panelists based on the demographic information obtained from the database proprietor.

Methods and apparatus to assign demographic information to panelists

Methods, apparatus, systems and articles of manufacture are disclosed to characterize households with media meter data. An example method includes identifying, with a processor, a target set of household categories associated with a target research geography, when a quantity of households within the target research geography representing the target set of household categories does not satisfy a threshold value, generating a first subset of categories and a second subset of categories from the target set of household categories, identifying a first set of households representing the first subset of categories from the target set of household categories and identifying an associated total number of household tuning minutes and a total number of household exposure minutes associated therewith, for each category in the second subset of categories from the target set of household categories, calculating a household tuning proportion and an exposure proportion, the household tuning proportion and exposure proportion based on the total number of household tuning minutes and exposure minutes, respectively, and calculating the panelist behavior probability based on the exposure proportion and the household tuning proportion.
