Methods and apparatus to determine informed holdouts for an advertisement campaign

摘要

Methods and apparatus are disclosed to determine informed holdouts for an advertisement campaign. An example storage medium includes instructions that, when executed, cause a machine to retrieve user identifiers associated with purchase instances; determine households that correspond to the user identifiers; identify a first and a second group type, the first group type exhibiting a first threshold of purchase behaviors, and the second group type exhibiting a second threshold of purchase behaviors; identify a first holdout group and a second holdout group, reduce computational lift calculation resource consumption by constraining the first holdout group to a first percentage, constraining the second holdout group to a second percentage, the first percentage equal to the second, the first and the second holdout groups are not to be exposed to an advertisement campaign; and determine a lift calculation for the advertisement campaign based on the first and the second holdout groups.
