Chapter 6: Missing Values

Definition of Missing Values

missing value

  • is a value that indicates that no data value is stored for the variable in the current observation. There are three kinds of missing values:

    • numeric

    • character

    • special numeric.

    By default, SAS prints a missing numeric value as a single period (.) and a missing character value as a blank space. See 'Special Missing Values' on page 102 for more information about special numeric missing values.
