Comparing SAS and Stata side by side | SAS Learning Modules

Additional Notes

• SAS represents missing values as "negative infinity" while Stata
  represents missing values as "positive infinity". For example, within Stata,
  numbers are ordered like this

  all nonmissing numbers < . < .a < .b < … < .z

  In SAS the order is reversed.

• Both SAS and Stata represent dates in a similar way, as the number of
  days before or since Jan 1 1960. So the date Jan 2 1960 is represented as a
  1 in both SAS and Stata.
• SAS permits you to have multiple active data files at once, while Stata
  only permits one active data file (in memory) at once.
