Statistics Finland - Quality guidelines - Statistical Editing and Imputation (263 words)
Statistical editing refers to activities by which the statistical data are checked and made as correct as possible with respect to both individual values and mutual compatibility between the values for different variables.
Statistical editing is needed at each phase, starting from the planning of the data collection all the way to data file formation and data processing and analysis.
Imputation implies that a missing value for a variable is replaced with an imputed value, which has to be as correct as possible with regard to the true but unknown value.
