Estimated Means: Custom Effects (generalized linear mixed models)
These are tables and charts for user-requested fixed all-factor effects.
Styles. There are different display styles, which are accessible from the Style dropdown list.
- Diagram. This style displays a line chart of the model-estimated
value of the target on the vertical axis for each value of the main
effect (or first listed effect in an interaction) on the horizontal
axis; a separate line is produced for each value of the second listed
effect in an interaction; a separate chart is produced for each value
of the third listed effect in a three-way interaction; all other predictors
are held constant.
If contrasts were requested, another chart is displayed to compare levels of the contrast field; for interactions, a chart is displayed for each level combination of the effects other than the contrast field. For pairwise contrasts, it is a distance network chart; that is, a graphical representation of the comparisons table in which the distances between nodes in the network correspond to differences between samples. Yellow lines correspond to statistically significant differences; black lines correspond to non-significant differences. Hovering over a line in the network displays a tooltip with the adjusted significance of the difference between the nodes connected by the line.
For deviation contrasts, a bar chart is displayed with the model-estimated value of the target on the vertical axis and the values of the contrast field on the horizontal axis; for interactions, a chart is displayed for each level combination of the effects other than the contrast field. The bars show the difference between each level of the contrast field and the overall mean, which is represented by a black horizontal line.
For simple contrasts, a bar chart is displayed with the model-estimated value of the target on the vertical axis and the values of the contrast field on the horizontal axis; for interactions, a chart is displayed for each level combination of the effects other than the contrast field. The bars show the difference between each level of the contrast field (except the last) and the last level, which is represented by a black horizontal line.
- Table. This style displays a table of the model-estimated
value of the target, its standard error, and confidence interval for
each level combination of the fields in the effect; all other predictors
are held constant.
If contrasts were requested, another table is displayed with the estimate, standard error, significance test, and confidence interval for each contrast; for interactions, there a separate set of rows for each level combination of the effects other than the contrast field. Additionally, a table with the overall test results is displayed; for interactions, there is a separate overall test for each level combination of the effects other than the contrast field.
Confidence. This toggles the display of upper and lower confidence limits for the marginal means, using the confidence level specified as part of the Build Options.
Layout. This toggles the layout of the pairwise contrasts diagram. The circle layout is less revealing of contrasts than the network layout but avoids overlapping lines.
