The set of analyzed process points can be limited merely to points representing
measured disturbances. In case the characteristics of individual process points are
strongly nonlinear there is a possibility of comparing current (antigen) and historical
(antibody) point values from vectors x and y.
The selection of x, y,andz vector elements, which are compared, defines the
process space
