We'll now easily compute age with the syntax below and we'll inspect its histogram to make sure the result has a plausible distribution. There are times when doing housekeeping on your sas libraries that you might want to know the age of your data sets. *inspect if result has plausible distribution.

A Slightly More Complex Routine Follows The Yrdif Function Which Calculates The Age Correctly.

As they are often used to calculate dates and times that are used in legal and financial applications. Calculate standard deviation by group. The following code shows how to calculate the standard deviation of points, grouped by team:

The Function “Mdy” Can Be Used To Create A Number From A Year, Month, And Day.

This function uses the following basic syntax: This might be useful when determining whether to delete old data sets, convert them to a newer release of sas, or archive them. (because, remember, a sas date is simply an integer representing the count of days since jan 1, 1960.).
