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.
