Methods, systems, articles of manufacture and apparatus to calibrate payload information

A non-transitory computer readable storage medium comprising instructions that, when executed, cause a machine to at least:

• obtain (a) passive measurement data and (b) background active measurement (BAM) data from panelists in a market of interest, the BAM data associated with network usage metrics of panelist wireless devices undisturbed by panelist behavior;
• assign a first share of the passive measurement data and a second share of the BAM data to particular areas within the market of interest, the first share based on a number of passive measurement occurrences in a first one of the particular areas, the second share based on a number of BAM occurrences in the first one of the particular areas;
• and
• remove a bias between the passive measurement data and the BAM data by calibrating the BAM data for the market of interest using weights determined for the first one of the particular areas based on the first and second shares.

A method comprising:

• obtaining, by executing one or more instructions with processor circuitry, (a) passive measurement data and (b) background active measurement (BAM) data from panelists in a market of interest, the BAM data associated with network usage metrics of panelist wireless devices undisturbed by panelist behavior;
• assigning, by executing one or more instructions with the processor circuitry, a first share of the passive measurement data and a second share of the BAM data to particular areas within the market of interest, the first share based on a number of passive measurement occurrences in a first one of the particular areas, the second share based on a number of BAM occurrences in the first one of the particular areas;
• and
• removing, by executing one or more instructions with the processor circuitry, a bias between the passive measurement data and the BAM data by calibrating the BAM data for the market of interest using weights determined for the first one of the particular areas based on the first and second shares.
