WebBecause post-survey adjustments are merely estimated “fixes” to the problem, the most effective way to reduce non-response bias is to reduce non-response rates through properly designed studies. Then the adjustments on the back-end will help reduce, but not eliminate, non-response bias. Webpoststratification, and raking, as well as, weight adjustment techniques that involve statistical modeling through logistic regression and generalized exponential models. To account for the nonresponse these weighting approaches rely on the assumption that the data is missing at random.
