In SPSS, how do I drop cases with missing values?

The SELECT command with the SYSMIS() function can drop all missing cases from the current SPSS data set. Consider the following:

SELECT IF NOT (SYSMIS(amount)). SAVE OUTFILE= 'newfile.sav'.

This example drops all cases whose value of the variable amount is missing, and then saves this data to an SPSS system file called newfile.sav.

If the dataset has more than one coding for missing values, as is often the case for survey data, select all of the different codings for missing values with the AND operator:

SELECT IF NOT (SYSMIS(amount1)) AND NOT (SYSMIS(amount2)). SAVE OUTFILE= 'newfile.sav'.

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.
