Simple imputation methods versus direct likelihood analysis for missing item scores in multilevel educational data.
Missing data, such as item responses in multilevel data, are ubiquitous in educational research settings. Researchers in the item response theory (IRT) context have shown that ignoring such missing data can create problems in the estimation of the IRT model parameters. Consequently, several imputation methods for dealing with missing item data have been proposed and shown to be effective when a...
متن کاملImputation with Item Nonrespondents
In clinical research, an instrument (or questionnaire) consisting of a number of items (or questions) is usually used to quantitate a subject’s behavior and the ability to function in day-to-day activities as perceived by the subject. For example, the EORTC QLQ-C30 questionnaire is commonly used as a reliable instrument to measure the quality of life of patients with cancer. On the other hand, ...
متن کاملItem Selection, Evaluation, and Simple Structure in Personality Data.
We report an investigation of the genesis and interpretation of simple structure in personality data using two very different self-reported data sets. The first consists of a set of relatively unselected lexical descriptors, whereas the second is based on responses to a carefully constructed instrument. In both data sets, we explore the degree of simple structure by comparing factor solutions t...
متن کاملMultiple Imputation of Item Scores in Test and Questionnaire Data, and Influence on Psychometric Results.
The performance of five simple multiple imputation methods for dealing with missing data were compared. In addition, random imputation and multivariate normal imputation were used as lower and upper benchmark, respectively. Test data were simulated and item scores were deleted such that they were either missing completely at random, missing at random, or not missing at random. Cronbach's alpha,...
متن کاملItem Imputation with the Discrete Edit System
The Fellegi-Holt algorithm (Fellegi and Holt 1976) provides a framework for item imputation by identifying for each record with one or more edit failures a minimal set of fields that must be imputed in order to satisfy a cohesive set of edits. The set of fields is minimal in the sense that there exists at least one joint value for the fields in the set such that, when this joint value is substi...
