MISSING Subcommand (CSTABULATE command)

The MISSING subcommand specifies how missing values are handled.

• All design variables must have valid data. Cases with invalid data for any design variable are deleted from the analysis.

The SCOPE keyword specifies which cases are used in the analyses. This specification is applied to tabulation variables but not design variables.

TABLE. Each table is based on all valid data for the tabulation variables used in creating the table. Tables for different variables may be based on different sample sizes. This is the default.

LISTWISE. Only cases with valid data for all tabulation variables are used in creating the tables. Tables for different variables are always based on the same sample size.

The CLASSMISSING keyword specifies whether user-missing values are treated as valid. This specification is applied to tabulation variables and categorical design variables (that is, strata, cluster, and subpopulation variables).

EXCLUDE. Exclude user-missing values. This is the default.

INCLUDE. Include user-missing values. Treat user-missing values as valid data.
