چکیده

We consider estimation of linear functionals of the joint law of regression models in which responses are missing at random. The usual approach is to work with the fully observed data, and to replace unobserved quantities by estimators of appropriate conditional expectations. Another approach is to replace all quantities by such estimators. We show that the second method is usually better than the first.

Generalized Family of Estimators for Imputing Scrambled Responses

When there is a high correlation between the study and the  auxiliary variables, the rank of the auxiliary variable also correlates with the study variable. Then, the use of the rank as an additional auxiliary variable may be helpful to increase the efficiency of the estimator of the mean or total of the population.   In the present study, we propose two  generalized familie...

Simple nuclear norm based algorithms for imputing missing data and forecasting in time series

There has been much recent progress on the use of the nuclear norm for the so-called matrix completion problem (the problem of imputing missing values of a matrix). In this paper we investigate the use of the nuclear norm for modelling time series, with particular attention to imputing missing data and forecasting. We introduce a simple alternating projections type algorithm based on the nuclea...

A Learning-based Model for Imputing Missing Levels in Partial Conjoint Profiles

A Learning-based Model for Imputing Missing Levels in Partial Conjoint Profiles Respondents in a conjoint experiment are sometimes presented with successive partial product profiles (i.e., profiles with missing attributes). The manner in which these respondents integrate available information in the current profile, information embedded in all previously shown profiles (perhaps through memory r...

Measuring and Reducing Inconsistency among Questionnaire Items through Imputation: An Application to the NSOPF

Most of the research work on imputation has concentrated on improving methods of imputing missing values a single variable at a time. For large complex surveys a more elaborate imputation process is needed, because the resulting data must satisfy various constraints and dependencies that are often intertwined. These constraints can take the form of one variable being the sum or ratio of others,...

Imputing Person Age for the 2000 Census

We present a model-based approach for imputing missing person age for the 2000 Census short form. We use a series of easy to implement multiple regression models, first proposed at the 1997 ASA Joint Meetings, to predict the missing age of a person. This paper extends our work by comparing our results with that of the hot-deck method used for the 1990 Census. By using a comprehensive set of inf...
