Living Costs and Food Survey 2008: VOLUME A, PART 4 Background Imputation of missing information Although LCF response is generally based on complete households responding, there are areas in the survey for which missing information is imputed. This falls into two broad categories: (i) Specific items of information missing from a response. These missing values are imputed on a case by case basis using other information collected in the interview.
