Effects of Unit Nonresponse on Estimating the Population Mean [PDF]

A Markov Chain Monte Carlo Multiple Imputation Procedure for Dealing with Item Nonresponse in the German SAVE Survey [PDF]

open access: yes
Important empirical information on household behavior is obtained from surveys. However, various interdependent factors that can only be controlled to a limited extent lead to unit and item nonresponse, and missing data on certain items is a frequent ...

Multiple imputation for unit-nonresponse versus weighting including a comparison with a nonresponse follow-up study [PDF]

open access: yes
The results of a national fear of crime survey are compared with results following the use of different nonresponse correction procedures. We compared naive estimates, weighted estimates, estimates after a thorough nonresponse follow-up and estimates ...

The interaction between unit and item nonresponse in view of the reverse cooperation continuum [PDF]

open access: yes
The paper addresses two questions. First, is item nonresponse (INR) a precursor of panel attrition (UNR), as predicted by the theory of a latent cooperation continuum, or is the interrelation of another type?

open access: yes, 2022
Imputation is a popular technique for handling item nonresponse. Parametric imputation is based on a parametric model for imputation and is not robust against the failure of the imputation model.
