PROVIDE Project Technical Paper 2005:1
originally contained ten or more ‘missing values’ are included in the table. The table shows
that the vast majority of these ‘missing values’ are in fact uncoded (column A). True missing
values make up a very small number of the total number of observations (columns B and F).
A number of observations were also miscoded, i.e. households that were expected to report
zero expenditure (or a missing value if Statistics South Africa had been consistent in their
treatment of optional sections) (column D). The sum of the ‘missing values’, miscoded
observations and the remaining non-zero values (column E) gives the total number of
observations in the database.
