Abstract:
|
We compared judgment post-stratification with simple random sample methods for estimating the probability of success when analyzing binary data subject to nonresponse. We believe that when nonresponse is related to the variable of interest, using judgment post-stratification provides additional information and leads to a reduction in bias under both perfect ranking and imperfect ranking. We illustrate this using primary care physician data on the use of Health Information Technology from the 2010 Ohio Medicaid HIT Survey for Health Care Professionals.
