Imputation is a method of determing values to replace missing data in the dataset. Imputation methods can draw from the nonmissing sample data as well as from information outside the sample. In NRI, imputation is also used for creating pseudo points to represent changes observed in PSU and county base data.

A statistical method used to generate values for missing items, designed to minimize the bias of estimates based on the resulting data set. In this survey, missing responses were generated using a procedure known as a "hot-deck imputation" which uses random resampling from similar nonmissing cases to generate values for missing cases.

Making an assumption about a missing value. E.g. if a survey respondent hasn't supplied his or her sex, and the person's occupation is Housewife, it's a reasonable imputation that the sex is female.

A statistical or logical technique by which missing data are inferred from other information provided by the respondent and/ or other respondents.

The act of imputing or charging; attribution; ascription; also, anything imputed or charged.

Charge or attribution of evil; censure; reproach; insinuation.

A setting of something to the account of; the attribution of personal guilt or personal righteousness of another; as, the imputation of the sin of Adam, or the righteousness of Christ.

Adam and Eve's sinful disobeying of Gods instruction when they ate the fruit of the tree of the knowledge of good and evil has been assigned to their children, their grandchildren, and all the way to present-day humanity forever. Holding one person responsible for the sins of another individual is rare in the field of religion and in secular moral systems. However, it is quite common in the Bible.
