The Densities options provide several ways to visually compare the distribution and composition of the response across the levels of the X factor. There are three density options:
• Compare Densities shows a smooth curve estimating the density of each group. The smooth curve is the density estimate for each group.
• Composition of Densities shows the summed densities, weighted by each group’s counts. At each X value, the Composition of Densities plot shows how each group contributes to the total.
• Proportion of Densities shows the contribution of the group as a proportion of the total at each X level.
The Densities options are not available when a Block variable is specified in the launch window.
