Elements of a document that can affect viewership are identified, monitored and recorded as change events. The numbers of computers, individuals or others viewing a publication (viewers) and what times they viewed it are collected from the appropriate source for the medium. One or more groups of change events for a given period of time are compared to the corresponding viewers via statistical regression to determine how much a given set of change events affects the changes in total viewers. |
