EMMEANS Subcommand (CSGLM command)

The EMMEANS subcommand displays estimated marginal means of the dependent variable in the cells for the specified factors. Note that these means are predicted, not observed, means.

• Multiple EMMEANS subcommands are allowed. Each subcommand is treated independently.
• The EMMEANS subcommand may be specified with no additional keywords. The output for an empty EMMEANS subcommand is the overall estimated marginal mean of the dependent variable, collapsing over any factors, and with any covariates held at their overall means.

TABLES = option. Valid options are factors appearing on the factor list and crossed factors that are constructed of factors on the factor list. Crossed factors can be specified by using an asterisk (*) or the keyword BY. All factors in a crossed factor specification must be unique. If a factor or a crossing of factors is specified on the TABLES keyword, CSGLM collapses over any other factors before computing the estimated marginal means for the dependent variable. If the TABLES keyword is not specified, the overall estimated marginal mean of the dependent variable, collapsing over any factors, is computed.

OTHER = [option]. Specifies the covariate values to use when computing the estimated marginal means. If the OTHER keyword is used, it must be followed by an equals sign and one or more elements enclosed in square brackets. Valid elements are covariates appearing on the CSGLM covariate list, each of which must be followed by a numeric value or the keyword MEAN in parentheses.

• If a numeric value is used, the estimated marginal mean will be computed by holding the specified covariate at the supplied value. If the keyword MEAN is used, the estimated marginal mean will be computed by holding the covariate at its overall mean. If a covariate is not specified on the OTHER option, its overall mean will be used in estimated marginal mean calculations.
• Any covariate may occur only once on the OTHER keyword.

CONTRAST = type. Specifies the type of contrast that is desired among the levels of the factor that is given on the COMPARE keyword. This keyword creates an L matrix such that the columns corresponding to the factor match the contrast that is given. The other columns are adjusted so that the L matrix is estimable. The CONTRAST keyword is ignored if the COMPARE keyword is not specified.

COMPARE = factor. Compares levels of a factor specified on the TABLES keyword and displays results for each individual comparison as well as for the overall set of comparisons. If only one factor is specified on TABLES, COMPARE can be specified by itself; otherwise, the factor specification is required. In the latter case, levels of the specified factor are compared for each level of the other factors that are specified on TABLES. The type of comparison that is performed is determined by the CONTRAST keyword. The TABLES keyword must be specified for the COMPARE keyword to be valid.
