CONTOUR=eps1,eps2,... BINORM=E(X),E(Y),S(X),S(Y),Corr(X,Y)
(in PLOT operation for scatter diagrams) determines the contour
ellipses to be plotted on levels eps1,eps2,... on the basis of the
two-dimensional normal distribution defined by a BINORM specification.
If BINORM is missing, the parameters are selected according to the plot-
ted data. The parameters eps1,eps2,... refer to the probabilities of
an observation to be found inside the ellipse. Particularly, eps1=0
causes the principal axes to be plotted.
Example: CONTOUR=0,0.5,0.9,0.99 BINORM=0,0,1,1,0.707
