# Complex Samples General Linear Model Options

**User-Missing Values.** All design variables, as well as
the dependent variable and any covariates, must have valid data.
Cases with invalid data for any of these variables are deleted from
the analysis. These controls allow you to decide whether user-missing
values are treated as valid among the strata, cluster, subpopulation,
and factor variables.

**Confidence Interval.** This is the confidence interval level
for coefficient estimates and estimated marginal means. Specify a
value greater than or equal to 50 and less than 100.
