The
Scree Plot
tab displays a plot of the
eigenvalue
for the ith component versus i to show the proportion of variation explained by the
principal components
. This tab is generated when the
Perform Principal Components Analysis
check box has been checked.
The
Scree Plot
tab is shown below:
The
Scree Plot
tab contains the following elements:
This
scree plot
for the principal components from the linear-bilinear model plots the eigenvalue by principal component in red and the cumulative proportion explained by the PCs in blue. This plot can give you an idea of the number of principal components that are needed to explain most of the
variance
.
