'''Hot-Deck Imputation''' replaces missing data with comparable data from the same set.  "Hot-deck imputation is a means of imputing data, using the data from other observations in the sample at hand." <ref>http://analytics.ncsu.edu/sesug/1999/075.pdf</ref>  For example, suppose census officials were unable to count the number of people in a given house and decided to fill in the missing data using hot-deck imputation.  They would use the data from a similar house in the same area, and substitute the number of people in that house for the missing data.  Hot-deck imputation is one of the most widely used imputation methods. <ref>http://nces.ed.gov/StatProg/2002/appendixb3.asp</ref>
