Abstract

Methods, apparatus, and articles of manufacture are disclosed to estimate population reach from marginal ratings with missing information. An example apparatus includes a pseudo universe calculator to (i) determine a first pseudo universe estimate for a first audience of media corresponding to a first union of first margins, the first margins corresponding to known audience totals, and (ii) determine a second pseudo universe estimate for a second audience of the media corresponding to a second union of second margins, the determination based on an audience constant, the second margins including a margin corresponding to an unknown audience total. The example apparatus also includes a reach calculator to (i) determine an estimate of the unknown audience total of the second audience based on the second pseudo universe estimate for the second audience, and (ii) determine a reach estimate for the second union based on the first and second pseudo universe estimates.

First claim

The invention claimed is:

1. A computing system comprising a processor and a memory, the computing system configured to perform a set of acts comprising:
determining a first ratings-independent universe estimate for a first audience total corresponding to a first union of a first piece of media and a second piece of the media, a first individual audience of the first piece of media to be known and a second individual audience of the second piece of the media to be known;
determining a second ratings-independent universe estimate for a second audience total corresponding to a second union of a third piece of the media and a fourth piece of the media, the determination of the second ratings-independent universe estimate based on an audience constant, at least one of the third piece of the media or the fourth piece of the media corresponding to an unknown audience portion included in the second audience total of the media; and
determining an estimate of the unknown audience portion based on the second ratings-independent universe estimate for the second audience total.

2. The computing system of claim 1 , wherein the set of acts further comprises generating a report based on the estimate of the unknown audience portion.

3. The computing system of claim 2 , wherein the set of acts further comprises outputting the report.

4. The computing system of claim 1 , wherein the set of acts further comprises determining the audience constant based on the first ratings-independent universe estimate, a reach of the first union, or respective known audience totals corresponding to the first piece of the media and the second piece of the media.

5. The computing system of claim 1 , wherein determining the first ratings-independent universe estimate comprises determining the first ratings-independent universe estimate based on a reach of the first union and respective known audience totals of the first piece of the media and the second piece of the media.

6. The computing system of claim 1 , wherein determining the second ratings-independent universe estimate comprises determining the second ratings-independent universe estimate based on the first ratings-independent universe estimate and a known audience total corresponding to at least one of the third piece of the media and the fourth piece of the media.

7. The computing system of claim 1 , wherein the unknown audience portion is an unknown universe audience portion.

8. A non-transitory computer-readable medium having stored therein instructions that when executed by a computing system cause the computing system to perform a set of acts comprising:
determining a first ratings-independent universe estimate for a first audience total corresponding to a first union of a first piece of media and a second piece of the media, a first individual audience of the first piece of media to be known and a second individual audience of the second piece of the media to be known;
determining a second ratings-independent universe estimate for a second audience total corresponding to a second union of a third piece of the media and a fourth piece of the media, the determination of the second ratings-independent universe estimate based on an audience constant, at least one of the third piece of the media or the fourth piece of the media corresponding to an unknown audience portion included in the second audience total of the media; and
determining an estimate of the unknown audience portion based on the second ratings-independent universe estimate for the second audience total.

9. The non-transitory computer-readable medium of claim 8 , wherein the set of acts further comprises generating a report based on the estimate of the unknown audience portion.

10. The non-transitory computer-readable medium of claim 9 , wherein the set of acts further comprises outputting the report.

11. The non-transitory computer-readable medium of claim 8 , wherein the set of acts further comprises determining the audience constant based on the first ratings-independent universe estimate, a reach of the first union, or respective known audience totals corresponding to the first piece of the media and the second piece of the media.

12. The non-transitory computer-readable medium of claim 8 , wherein determining the first ratings-independent universe estimate comprises determining the first ratings-independent universe estimate based on a reach of the first union and respective known audience totals of the first piece of the media and the second piece of the media.

13. The non-transitory computer-readable medium of claim 8 , wherein determining the second ratings-independent universe estimate comprises determining the second ratings-independent universe estimate based on the first ratings-independent universe estimate and a known audience total corresponding to at least one of the third piece of the media and the fourth piece of the media.

14. The non-transitory computer-readable medium of claim 8 , wherein the unknown audience portion is an unknown universe audience portion.

15. A method comprising:
determining, by a computing system, a first ratings-independent universe estimate for a first audience total corresponding to a first union of a first piece of media and a second piece of the media, a first individual audience of the first piece of media to be known and a second individual audience of the second piece of the media to be known;
determining, by the computing system, a second ratings-independent universe estimate for a second audience total corresponding to a second union of a third piece of the media and a fourth piece of the media, the determination of the second ratings-independent universe estimate based on an audience constant, at least one of the third piece of the media or the fourth piece of the media corresponding to an unknown audience portion included in the second audience total of the media; and
determining, by the computing system, an estimate of the unknown audience portion based on the second ratings-independent universe estimate for the second audience total.

16. The method of claim 15 , further comprising generating a report based on the estimate of the unknown audience portion.

17. The method of claim 16 , further comprising outputting the report.

18. The method of claim 15 , further comprising determining the audience constant based on the first ratings-independent universe estimate, a reach of the first union, or respective known audience totals corresponding to the first piece of the media and the second piece of the media.

19. The method of claim 15 , wherein determining the first ratings-independent universe estimate comprises determining the first ratings-independent universe estimate based on a reach of the first union and respective known audience totals of the first piece of the media and the second piece of the media.

20. The method of claim 15 , wherein determining the second ratings-independent universe estimate comprises determining the second ratings-independent universe estimate based on the first ratings-independent universe estimate and a known audience total corresponding to at least one of the third piece of the media and the fourth piece of the media.
