In SPSS, how can I generate variables with random values?

In SPSS, the following example generates two variables, named x and y , with 100 cases each. The variable x is drawn from a normal distribution with zero mean and a standard deviation of one. The variable y is drawn from a uniform distribution ranging between zero and one. The code is as follows:

INPUT PROGRAM. LOOP #i=1 to 100. COMPUTE id=#i. COMPUTE x=RV.NORMAL(0,1). COMPUTE y=RV.UNIFORM(0,1). END CASE. END LOOP. END FILE. END INPUT PROGRAM. EXECUTE.

You can also choose other distributions, such as beta, chi-squared, and F.

For more about statistical and mathematical software, email the UITS Stat/Math Center, visit the center's web page, or phone 812-855-4724 (IUB) or 317-278-4740 (IUPUI). The center is located in Bloomington at 410 N. Park Avenue, and is open for consultation by appointment Monday-Friday 9am-5pm.
