Methods and apparatus to determine synthetic respondent level data

An apparatus comprising:

• a station translator to:
• identify locations corresponding to monitored panelists;
• when a location of the identified locations corresponds to two or more affiliates, sum tuning minutes of the two or more affiliates;
• generate an affiliate probability based on the sum;
• and
• convert first data of households in the location to a candidate receivability session based on the affiliate probability;
• and
• a seed panel generator to:
• generate a seed panel, the seed panel to include at least one of the monitored panelists selected based on a population associated with return path data;
• and
• donate second data associated with a donor pool of first panelists to second panelists included in the seed panel, the second panelists associated with faulty media monitoring equipment.

A non-transitory computer readable medium comprising instructions which, when executed, cause one or more processors to at least:

• identify locations corresponding to monitored panelists;
• when a location of the identified locations corresponds to two or more affiliates, sum tuning minutes of the two or more affiliates;
• generate an affiliate probability based on the sum;
• convert first data of households in the location to a candidate receivability session based on the affiliate probability;
• generate a seed panel, the seed panel to include at least one of the monitored panelists selected based on a population associated with return path data;
• and
• donate second data associated with a donor pool of first panelists to second panelists included in the seed panel when the second panelists are included in the seed panel, the second panelists corresponds to faulty media monitoring equipment.
