3. A computer implemented method as defined in claim 2 , further including determining, for the respective purchase groups, an incremental purchase amount of the brand of interest based on a difference value of respective adjacent purchase group purchases.

4. A computer implemented method as defined in claim 3 , further including determining, for the respective purchase groups, a long-term sales effect multiplier based on a ratio of (a) the incremental purchase amount of the brand of interest and (b) an average brand product purchase amount during an introductory period of the marketing stimulus.

5. A computer implemented method as defined in claim 3 , further including determining, for the respective purchase groups, a long-term brand multiplier based on a sum of respective long-term sales effect multipliers divided by a total number of the respective purchase groups.

6. A computer implemented method as defined in claim 2 , wherein the category purchase amount for the brand of interest includes an average category purchase amount.

7. A computer implemented method as defined in claim 1 , wherein the subsequent product unassociated with the brand of interest is associated with a category associated with the brand of interest.

8. A computer implemented method as defined in claim 1 , further including setting a target value of the consecutive purchase occasion values based on a category type of the product.

9. An apparatus to improve an efficiency of marketing campaign computing resource allocation, the apparatus comprising:

a participant purchase monitor to identify, for respective participants, a trial purchase of a first product associated with a brand of interest following a marketing stimulus for the brand of interest;

a purchase depth manager to:

increment, for the respective participants, a brand purchase count of purchase occasions when a subsequent product associated with the brand of interest is purchased during a first period of time;

reset, for the respective participants, the brand purchase count to zero when a subsequent product unassociated with the brand of interest is purchased during the first period of time; and

prevent heuristic error by generating purchase groups indicative of consecutive purchase occasion values of the respective participants based on respective highest values of the brand purchase count, the consecutive purchase occasion values indicative of brand purchase instances not interrupted by purchase instances unassociated with the brand of interest; and

an extended value calculator to:

calculate a first sales effect for the respective purchase groups based on the respective values of the brand purchase count, the first sales effect associated with the first period of time; and

improve the efficiency of a marketing campaign computing resource allocation by comparing the first sales effect to a second sales effect, the second sales effect associated with a second period of time, the comparison to prevent computational waste by identifying a type of marketing activity associated with a larger one of the first sales effect or the second sales effect.

10. An apparatus as defined in claim 9 , wherein the extended value calculator is to determine a category purchase amount for the brand of interest within a measurement period following an exposure period of the marketing stimulus.

11. An apparatus as defined in claim 10 , wherein the extended value calculator is to determine an incremental purchase amount of the brand of interest based on a difference value of respective adjacent purchase group purchases.

12. An apparatus as defined in claim 11 , wherein the extended value calculator is to determine a long-term sales effect multiplier based on a ratio of (a) the incremental purchase amount of the brand of interest and (b) an average brand product purchase amount during an introductory period of the marketing stimulus.

13. An apparatus as defined in claim 11 , wherein the extended value calculator is to determine a long-term brand multiplier based on a sum of respective long-term sales effect multipliers divided by a total number of the respective purchase groups.

14. An apparatus as defined in claim 9 , wherein the purchase depth manager is to identify that the subsequent product unassociated with the brand of interest is associated with a category associated with the brand of interest.

15. An apparatus as defined in claim 9 , wherein the purchase depth manager is to set a target value of the consecutive purchase occasion values based on a category type of the product.

16. A tangible computer readable storage medium comprising computer readable instructions that, when executed, cause a processor to at least:

for respective participants, identify a trial purchase of a first product associated with a brand of interest following a marketing stimulus for the brand of interest;

for the respective participants, increment a brand purchase count of purchase occasions when a subsequent product associated with the brand of interest is purchased during a first period of time;

for the respective participants, reset the brand purchase count to zero when a subsequent product unassociated with the brand of interest is purchased during the first period of time;

prevent heuristic error by generating purchase groups indicative of consecutive purchase occasion values of the respective participants based on respective highest values of the brand purchase count, the consecutive purchase occasion values indicative of brand purchase instances not interrupted by purchase instances unassociated with the brand of interest;

calculate a first sales effect for the respective purchase groups based on the respective values of the brand purchase count, the first sales effect associated with the first period of time; and
