Methods and apparatus to characterize households with media meter data
View Patent ↗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 household minute credited to a station in a household by a first media meter (MM) device, the first MM device collecting only audio data, determining whether a panelist audience meter device is crediting the station at the same time in the household, when the panelist audience meter device is crediting the same station, associating the household minute with an ambient tuning status, identifying a first automatic gain control (AGC) value and a first code status of the household minute, calculating model coefficients based on the ambient tuning status, the first AGC value and the first code status, and calculating a probability of ambient tuning based on the model coefficients.
1. A method to calculate a probability of ambient tuning, comprising:
identifying, with a processor, a household minute credited to a station in a household by a first media meter (MM) device, the first MM device collecting only audio data;
determining, with the processor, whether a panelist audience meter device is crediting the station at the same time in the household;
reducing overreporting of the household when the panelist audience meter device is crediting the same station by associating, with the processor, the household minute with an ambient tuning status;
identifying, with the processor, a first automatic gain control (AGC) value and a first code status of the household minute;
calculating, with the processor, model coefficients based on the ambient tuning status, the first AGC value and the first code status; and
calculating, with the processor, a probability of ambient tuning based on the model coefficients.
2. A method as defined in claim 1 , further including applying the model coefficients to data from a second MM device in a second household, the second household devoid of a panelist audience meter device.
3. A method as defined in claim 2 , further including applying collected household tuning minutes data from the second MM device to a model with the coefficients to calculate the probability of ambient tuning.
4. A method as defined in claim 3 , wherein the collected household tuning minute data includes second AGC values and a second code status.
5. A method as defined in claim 1 , wherein the code status includes at least one of no detected codes, some detected codes or codes detected in all minutes.
6. A method as defined in claim 5 , further including determining whether detected codes are stacked or unstacked.
7. A method as defined in claim 6 , wherein calculating model coefficients includes a stacked/unstacked status.
8. An apparatus to calculate a probability of ambient tuning, comprising:
a crediting manager to identify a household minute credited to a station in a household by a first media meter (MM) device, the first MM device collecting only audio data;
a station comparator to determine whether a panelist audience meter device is crediting the station at the same time in the household;
when the panelist audience meter device is crediting the same station, reducing overreporting of the household with a tuning type assignor to associate the household minute with an ambient tuning status;
an automatic gain control (AGC) monitor to identify a first AGC value and a first code status of the household minute; and
a modeling engine to calculate model coefficients based on the ambient tuning status, the first AGC value and the first code status, and to calculate a probability of ambient tuning based on the model coefficients.
9. An apparatus as defined in claim 8 , wherein the modeling engine is to apply the model coefficients to data from a second MM device in a second household, the second household devoid of a panelist audience meter device.
10. An apparatus as defined in claim 9 , wherein the modeling engine is to apply collected household tuning minutes data from the second MM device to a model with the coefficients to calculate the probability of ambient tuning.
11. An apparatus as defined in claim 10 , wherein the collected household tuning minute data includes second AGC values and a second code status.
12. An apparatus as defined in claim 8 , wherein the code status includes at least one of no detected codes, some detected codes or codes detected in all minutes.
13. An apparatus as defined in claim 12 , further including a code stacking manager to determine whether detected codes are stacked or unstacked.
14. An apparatus as defined in claim 13 , wherein the modeling engine is to calculate model coefficients based on the stacked or unstacked status.
15. A tangible machine readable storage medium comprising instructions that, when executed, cause a machine to at least:
identify a household minute credited to a station in a household by a first media meter (MM) device, the first MM device collecting only audio data;
determine whether a panelist audience meter device is crediting the station at the same time in the household;
reduce overreporting of the household when the panelist audience meter device is crediting the same station by associating the household minute with an ambient tuning status;
identify a first automatic gain control (AGC) value and a first code status of the household minute;
calculate model coefficients based on the ambient tuning status, the first AGC value and the first code status; and
calculate a probability of ambient tuning based on the model coefficients.
16. A storage medium as defined in claim 15 , wherein the instructions, when executed, further cause the machine to apply the model coefficients to data from a second MM device in a second household, the second household devoid of a panelist audience meter device.
17. A storage medium as defined in claim 16 , wherein the instructions, when executed, further cause the machine to apply collected household tuning minutes data from the second MM device to a model with the coefficients to calculate the probability of ambient tuning.
18. A storage medium as defined in claim 17 , wherein the instructions, when executed, further cause the machine to include second AGC values and a second code status within the collected household tuning minute data.
19. A storage medium as defined in claim 15 , wherein the instructions, when executed, further cause the machine to identify a code status of at least one of no detected codes, some detected codes or codes detected in all minutes.
20. A storage medium as defined in claim 19 , wherein the instructions, when executed, further cause the machine to determine whether detected codes are stacked or unstacked.
21. A storage medium as defined in claim 20 , wherein the instructions, when executed, further cause the machine to include a stacked/unstacked status when calculating model coefficients.
