Title:
Mister P: Challenges in Generalizing from Sample to Population
Abstract:
With internet surveys, nonrepresentativeness and nonresponse are bigger concerns
than ever. The natural approach is to adjust for more information, demographic
and otherwise, to align the sample with the population. We demonstrate the
effectiveness of multilevel regression and poststratification (MRP, or Mister P) in
internet surveys, and we also discuss some of the challenges and risks of this and
other approaches.
