The estimation of R 2 and adjusted R 2 in incomplete data sets using multiple imputation

Harel, Ofer·2009·Journal of Applied Statistics

Abstract

The coefficient of determination, known also as the R 2, is a common measure in regression analysis. Many scientists use the R 2 and the adjusted R 2 on a regular basis. In most cases, the researchers treat the coefficient of determination as an index of ‘usefulness’ or ‘goodness of fit,’ and in some cases, they even treat it as a model selection tool. In cases in which the data is incomplete, most researchers and common statistical software will use complete case analysis in order to estimate the R 2, a procedure that might lead to biased results. In this paper, I introduce the use of multiple imputation for the estimation of R 2 and adjusted R 2 in incomplete data sets. I illustrate my methodology using a biomedical example.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
