Scatter Plot Matrix
Scatter plots are displayed for pairs of variables.
Without X variables, scatter plots are displayed as
a symmetric matrix containing each pair of Y variables.
With a nominal Y variable, scatter plots are displayed as
a symmetric matrix containing each pair of X variables.
When both interval Y variables and interval X variables
are selected, scatter plots are displayed as
a rectangular matrix with Y variables as the row variables
and X variables as the column variables.

matrix with 80% prediction confidence ellipses.
