MISSING Subcommand (SPCHART command)

MISSING controls the treatment of missing values.

• The default is NOREPORT and EXCLUDE.
• REPORT and NOREPORT are alternatives and apply only to category variables. REPORT and NOREPORT control whether categories (subgroups) with missing values are created. They do not apply to process capability charts (/CPCHART).
• INCLUDE and EXCLUDE are alternatives and apply to process variables.

NOREPORT. Suppress missing-value categories. This setting is the default.

REPORT. Report and plot missing-value categories.

EXCLUDE . Exclude user-missing values. Both user-missing and system-missing values for the process variable are excluded from computation and plotting. This setting is the default.

INCLUDE . Include user-missing values. Only system-missing values for the process variable are excluded from computation and plotting.
