Methods and apparatus to determine synthetic respondent level data
View Patent ↗Methods, apparatus, systems, and articles of manufacture are disclosed to generate synthetic respondent level data. An example method includes generating, by executing an instruction with a processor, a seed panel, the seed panel including monitored panelists selected based on a population associated with return path data; comparing, by executing an instruction with the processor, a target rating to a current rating corresponding to the seed panel; and adjusting, by executing an instruction with the processor, the seed panel based on the comparison.
1. An apparatus comprising:
a seed panel generator to generate a seed panel, the seed panel to include monitored panelists selected based on a population associated with return path data the seed panel generator to donate data associated with a donor pool of panelists to out-of-tab panelists included in the seed panel when the out-of-tab panelists are included in the seed panel; and
a seed panel optimizer to:
compare a target rating to a computed rating determined based on the seed panel; and
adjust the seed panel based on the comparison to reduce an error between the target rating and the computed rating.
2. The apparatus of claim 1 , wherein the target rating is determined based on the return path data and corresponds to a first percentage of persons of a first demographic exposed to first media at a first time.
3. The apparatus of claim 2 , wherein the computed rating corresponds to a second percentage of seed panelists exposed to the first media at the first time.
4. The apparatus of claim 1 , wherein the seed panel generator is to assign at least one of geography data or income data to the return path data based on demographics associated with the population.
5. The apparatus of claim 4 , wherein the seed panel generator is to:
select a first group of the monitored panelists to be seed panelists based on a comparison of the monitored panelists and the at least one of the geography data or the income data assigned to the return path data; and
weight the seed panelists based on a universe estimate of media users.
6. The apparatus of claim 1 , wherein the seed panel generator is to at least one of replicate or down-sample seed panelists.
7. The apparatus of claim 1 , wherein the seed panel optimizer is to adjust the seed panel based on a viewership error corresponding to the seed panel.
8. The apparatus of claim 7 , wherein the viewership error is based on a constraint corresponding to the target rating, and the seed panel optimizer is to iteratively adjust the seed panel until the constraint corresponding to the target rating is satisfied.
9. The apparatus of claim 1 , wherein the seed panel optimizer is to generate a file including respondent level data corresponding to the adjusted seed panel.
10. A method comprising:
generating, by executing an instruction with a processor, a seed panel, the seed panel including monitored panelists selected based on a population associated with return path data, the generating of the seed panel including donating viewing data associated with a donor pool of panelists to out-of-tab panelists included in the seed panel when the out-of-tab panelists are included in the seed panel;
comparing, by executing an instruction with the processor, a target rating to a computed rating determined based on the seed panel; and
adjusting, by executing an instruction with the processor, the seed panel based on the comparison to reduce an error between the target rating and the computed rating.
11. The method of claim 10 , wherein the target rating is determined based on the return path data and corresponds to a first percentage of persons of a first demographic of the population exposed to first media at a first time.
12. The method of claim 11 , wherein the computed rating corresponds to a second percentage of seed panelists exposed to the first media at the first time.
13. The method of claim 10 , further including assigning at least one of geography data or income data to the return path data based on demographics associated with the population.
14. The method of claim 13 , wherein the generating of the seed panel includes:
selecting a first group of the monitored panelists to be seed panelists based on a comparison of the monitored panelists and the at least one of the geography data or the income data assigned to the return path data; and
weighting the seed panelists based on a universe estimate of media users.
15. The method of claim 10 , wherein the generating of the seed panel further includes at least one of replicating or down-sampling seed panelists.
16. The method of claim 10 , wherein the adjusting of the seed panel includes adjusting the seed panel based on a viewership error corresponding to the seed panel.
17. The method of claim 16 , wherein the viewership error is based on a constraint corresponding to the target rating, and the seed panel is iteratively adjusted until the constraint corresponding to the target rating is satisfied.
18. A tangible computer readable storage medium comprising instructions which, when executed, cause a processor to at least:
generate a seed panel, the seed panel to include monitored panelists selected based on a population associated with return path data;
donate viewing data associated with a donor pool of panelists to out-of-tab panelists included in the seed panel when the out-of-tab panelists are included in the seed panel;
compare a target rating to a computed rating determined based on the seed panel; and
adjust the seed panel based on the comparison to reduce an error between the target rating and the computed rating.
19. The tangible computer readable storage medium of claim 18 , wherein the target rating is determined based on the return path data and corresponds to a first percentage of persons of a first demographic of the population exposed to first media at a first time.
20. The tangible computer readable storage medium of claim 19 , wherein the computed rating corresponds to a second percentage of seed panelists exposed to the first media at the first time.
21. The tangible computer readable storage medium of claim 18 , wherein the instructions cause the processor to assign at least one of geography data or income data to the return path data based on demographics associated with the population.
22. The tangible computer readable storage medium of claim 21 , wherein the instructions cause the processor to:
select a first group of the monitored panelists to be seed panelists based on a comparison of the monitored panelists and the at least one of the geography data or the income data assigned to the return path data; and
weight the seed panelists based on a universe estimate of media users.
23. The tangible computer readable storage medium of claim 18 , wherein the instructions cause the processor to, at least one of replicate or down-sample seed panelists.
24. The tangible computer readable storage medium of claim 18 , wherein the instructions cause the processor to adjust the seed panel based on a viewership error corresponding to the seed panel.
25. The tangible computer readable storage medium of claim 24 , wherein the viewership error is based on a constraint corresponding to the target rating, and the instructions cause the processor to iteratively adjust the seed panel until the constraint corresponding to the target rating is satisfied.
26. The tangible computer readable storage medium of claim 18 , wherein the instructions cause the processor to generate a file including respondent level data corresponding to the adjusted seed panel.
