Description: According to the Statistical Terminology glossary maintained by the National Science Foundation, this is "the process by which one estimates missing values for items that a survey respondent failed to provide," and if applicable in this context, it refers to the type of procedure used. When applied to an nCube, imputation takes into consideration all of the dimensions that are part of that nCube.
