EMMEANS_OPTIONS Subcommand (GENLINMIXED command)

The EMMEANS_OPTIONS subcommand contains specifications that are used across all EMMEANS subcommands.

CONTROL Keyword

The CONTROL keyword specifies the covariate values to use when computing the estimated marginal means.

• Specify one or more covariates appearing on the FIXED subcommand EFFECTS list, each of which must be followed by a numeric value.
• If a covariate is not specified on the CONTROL option, then its overall mean will be used in estimated marginal means calculations.
• Any covariate can occur only once on the CONTROL keyword.

SCALE Keyword

The SCALE keyword specifies whether to compute estimated marginal means based on the original scale of the target or based on the link function transformation.

ORIGINAL. Estimated marginal means are based on the original scale of the target. Estimated marginal means are computed for the target. This is the default. Note that when the target is specified using the events/trials option, ORIGINAL gives the estimated marginal means for the events/trials proportion rather than for the number of events.

TRANSFORMED. Estimated marginal means are based on the link function transformation. Estimated marginal means are computed for the linear predictor.

PADJUST Keyword

The PADJUST keyword indicates the method of adjusting the significance level.

LSD. Least significant difference. This method does not control the overall probability of rejecting the hypotheses that some linear contrasts are different from the null hypothesis value(s). This is the default.

SEQBONFERRONI. Sequential Bonferroni. This is a sequentially step-down rejective Bonferroni procedure that is much less conservative in terms of rejecting individual hypotheses but maintains the same overall significance level.

SEQSIDAK. Sequential Sidak. This is a sequentially step-down rejective Sidak procedure that is much less conservative in terms of rejecting individual hypotheses but maintains the same overall significance level.
