Estimation Procedures, 1996

Statistics presented in the 1996 National Home and Hospice Care Survey were derived by a multistage estimation procedure that produces essentially unbiased national estimates and has three principal components. The first component, inflation by the reciprocals of the probabilities of sample selection, is the basic inflation weight. This component consists of the inverse of the probability of selecting the agency and the patient or discharge within each agency. The second component, which consists of an adjustment for nonresponse, brings estimates based only on the responding cases up to the level that would have been achieved if all eligible cases had responded. The third component, ratio adjustment to fixed totals, adjusts for over or undersampling of agencies reported in the sampling frame.
