The
Variance Components Charts
tab contains the following elements:
This
bar chart
provides an overall view of proportion of variability explained by all specified
variance
components, as well as a "Residual" component that models all unexplained variability. The height of each bar is computed via a weighted average of variance component estimates computed from
principal components
, weighting by
eigenvalues
. This chart can reveal the major sources of variability in your experiment.
This
overlay plot
shows the profile of each principal variance component across specified effects. It reveals how each principal variance component aligns with each effect. Effects with large bars in the first plot should have large peaks in this plot, and the color indicates which principal component picked up on it.
