Complex Samples Ratios Missing Values

Ratios. This group determines which cases are used in the analysis.

• Use all available data. Missing values are determined on a ratio-by-ratio basis. Thus, the cases used to compute statistics may vary across numerator-denominator pairs.
• Ensure consistent case base. Missing values are determined across all variables. Thus, the cases used to compute statistics are consistent.

Categorical Design Variables. This group determines whether user-missing values are valid or invalid.
