Weighted Hotdeck Imputation
نویسندگان
چکیده
Hotdeck imputation replaces missing lines of data by sampled complete data records. The theory underpinning this method was published over a decade ago (Rubin and Schenker1986), and since its conception has remained predominantly unchanged. Most of the research involving hotdeck imputation has been in the area of constructing strata, which are used to impute within (independently), notably the propensity score (Rosenbaum and Rubin1984). This paper extends these ideas by using the actual propensity score in a weighted hotdeck imputation procedure. The weighted hotdeck is compared to the original hotdeck using simulated data examples and a real data example previously covered in (Pickles .1995). The real data example demonstrates an application of multiple imputation when the missing data is by design.

1 Weighted Sequential Hot Deck Imputation : SAS Macro vs . SUDAAN ’ s PROC
Item non-response is a challenge faced by virtually all surveys. Item non-response occurs when a respondent skips over a question, refuses to answer a question, or indicates that they do not know the answer to a question. Hot deck imputation is one of the primary item non-response imputation tools used by survey statisticians. Recently, new competitor in the field of Weighted Sequential Hotdeck...
متن کاملPseudo-GEE Approach to Analyzing Longitudinal Surveys under Imputation for Missing Responses
This paper presents a pseudo-GEE approach to the analysis of longitudinal surveys when the response variable contains missing values. A cycle-specific marginal hotdeck imputation method is proposed to fill in the missing responses and the pseudo-GEE method described in Carrillo et al. (2009) is applied to the imputed data set. Consistency of the resulting pseudo-GEE estimators is established un...
متن کاملDeveloping Imputation Models for the Services Sectors Portion of the Economic Census
The editing software used by the Economic Census offers a variety of imputation options, many of which employ statistical models. In prior censuses, the services sectors portion of the Economic Census has relied on industry average imputation as its primary statistical imputation model. This ratio imputation method uses weighted least squares estimates for no-intercept simple linear regression ...
متن کاملImproved methods for the imputation of missing data by nearest neighbor methods
Missing data is an important issue in almost all fields of quantitative research. A nonparametric procedure that has been shown to be useful is the nearest neighbor imputation method. We suggest a weighted nearest neighbor imputation method based on Lq-distances. The weighted method is shown to have smaller imputation error than available NN estimates. In addition we consider weighted neighbor ...
متن کاملMultiple imputation analysis of case-cohort studies.
The usual methods for analyzing case-cohort studies rely on sometimes not fully efficient weighted estimators. Multiple imputation might be a good alternative because it uses all the data available and approximates the maximum partial likelihood estimator. This method is based on the generation of several plausible complete data sets, taking into account uncertainty about missing values. When t...
