This makes it difficult or impossible to anticipate the pattern of missing data values in advance (e.g. during algorithm design time or deployment time).
  • Another problem may the ambiguity caused by missing data values. For example, when data values represent a measured quantity (numerical quantity), a missing data value may be indicated by the value zero.
  • a non-missing data values with a measured quantity equal to zero may also be indicated by the value zero.
