SAS programming lecture 4:

Homework 1 is due today, please remember to turn in a hard copy of your code as well as sending me the information via email. Also remember to write on your hard copy of your code what previous statistics courses you have had.

Drawing (pseudo) random samples

• Pseudo random number generators
• Use of the seed value: for seed <= 0 SAS uses the system clock; for seed > 0 that number is used

Use of simulation to assess level and power of a statistical procedure

• Using simple DO loops, the OUTPUT statement, PROC GLM options

Logical statements

• Simple IF ( ) THEN ( ) statements
• The ELSE statement
• Selecting and deleting cases; detecting the end of a file
• Executing a block of statements after IF ( ) THEN
• the RETAIN statement, accumulators, and counters
