Abstract

Methods, apparatus, systems to determine a conditional probability based on audience member probability distributions for media audience measurement are disclosed. Disclosed example methods for media audience measurement include determining a first audience probability distribution for a first member of a household and determining a second audience probability distribution for a second member of the household. Disclosed example methods also include calculating probabilities for audience combinations of the first member and the second member of the household based on the first audience probability distribution and the second audience probability distribution. Disclosed example methods further include determining a household audience characteristic probability based on the calculated probabilities of the audience combinations of the household. The household audience characteristic indicates likelihoods of different possible audience compositions of the household for a media event.

First claim

What is claimed is:

1. A method for media audience measurement, the method comprising:
obtaining, by executing an instruction with one or more processors of a remote computing system, exposure data indicating a number of occurrences in which respective members of a household were exposed to a media event, wherein the exposure data is generated in association with the household and obtained over a network from a local computing system located within the household;
based on the exposure data, determining, by executing an instruction with the one or more processors, a first audience probability distribution for a first member of the household, the first audience probability distribution modeling a likelihood for a given occurrence of the first member being exposed to the media event;
based on the exposure data, determining, by executing an instruction with the one or more processors, a second audience probability distribution for a second member of the household, the second audience probability distribution modeling a likelihood for a given occurrence of the second member being exposed to the media event;
based on the first audience probability distribution and the second audience probability distribution, calculating, by executing an instruction with the one or more processors, a respective exposure probability for each of at least three different sets of audience members, the at least three sets of audience members including the first member alone, the second member alone, and the first and second members together; and
based on calculated exposure probabilities, determining a co-viewing likelihood that the first member and the second member were exposed to the media event.

2. The method of claim 1 , further including:
generating, by executing an instruction with one or more processors of a local computing system that is located within the household, the exposure data, wherein generating the exposure data includes generating exposure data that includes one or more of presence information for the respective members of the household or identifiers for the respective members of the household; and
transmitting, by executing an instruction with the one or more processors of the local computing system, the exposure data to the remote computing system.

3. The method of claim 2 , further including generating, by executing an instruction with the one or more processors of the local computing system, a prompt for the respective members to provide one or more of the presence information or the identifiers.

4. The method of claim 1 , wherein determining the first audience probability distribution is based on (a) a first count indicative of the number of occurrences in which the first member was exposed to the media event and (b) a second count indicative of a number of occurrences in which the first member was not exposed to the media event, the second count based on the exposure data.

5. The method of claim 4 , further including determining, by executing an instruction with the one or more processors, the first audience probability distribution based on a beta distribution or a Dirichlet distribution.

6. The method of claim 4 , wherein the first count is indicative of the number of occurrences in which the first member was exposed to the media event via a first media presentation device in the household, and further including determining, by executing an instruction with the one or more processors, the first audience probability distribution based on the first count, the second count, and a third count, the third count indicative of a number of occurrences in which the first member was exposed to the media event via a second media presentation device in the household.

7. The method of claim 1 , further including calculating, by executing an instruction with the one or more processors, the exposure probabilities based on values randomly selected from one or more of the first audience probability distribution or the second audience probability distribution.

8. A system comprising:
interface circuitry;
machine readable instructions; and
programmable circuitry to execute the machine readable instructions to at least:
obtain exposure data indicating a number of occurrences in which respective members of a household were exposed to a media event, the exposure data generated in association with the household and obtained over a network from a local computing system located within the household;
based on the exposure data, determine a first audience probability distribution for a first member of the household, the first audience probability distribution modeling a likelihood for a given occurrence of the first member being exposed to the media event;
based on the exposure data, determine a second audience probability distribution for a second member of the household, the second audience probability distribution modeling a likelihood for a given occurrence of the second member being exposed to the media event;
based on the first audience probability distribution and the second audience probability distribution, calculate a respective exposure probability for each of at least three different sets of audience members, the at least three sets of audience members including the first member alone, the second member alone, and the first and second members together; and
based on calculated exposure probabilities, determine a co-viewing likelihood that the first member and the second member were exposed to the media event.

9. The system of claim 8 , wherein the exposure data includes one or more of presence information for the respective members of the household or identifiers for the respective members of the household.

10. The system of claim 9 , wherein the programmable circuitry is to cause a prompt for the respective members to provide one or more of the presence information or the identifiers to be generated.

11. The system of claim 8 , wherein the programmable circuitry is to determine the first audience probability distribution based on (a) a first count indicative of the number of occurrences in which the first member was exposed to the media event and (b) a second count indicative of a number of occurrences in which the first member was not exposed to the media event, the second count based on the exposure data.

12. The system of claim 11 , wherein the programmable circuitry is to determine the first audience probability distribution based on a beta distribution or a Dirichlet distribution.

13. The system of claim 11 , wherein the first count is indicative of the number of occurrences in which the first member was exposed to the media event via a first media presentation device in the household, the programmable circuitry to determine the first audience probability distribution based on the first count, the second count, and a third count, the third count indicative of a number of occurrences in which the first member was exposed to the media event via a second media presentation device in the household.

14. The system of claim 8 , wherein the programmable circuitry is to calculate the exposure probabilities based on values randomly selected from one or more of the first audience probability distribution or the second audience probability distribution.

15. A non-transitory machine readable storage medium comprising instructions to cause programmable circuitry to at least:
obtain exposure data indicating a number of occurrences in which respective members of a household were exposed to a media event, wherein the exposure data is generated in association with the household and obtained over a network from a local computing system locat
