The process parameter 8 (O<g<1) implicates the so called 
correlation distance rr. 
+ = 2.146 / (1-8) (4) 
1 is defined as the number i of steps, two variables ry 
and Petri must be seperated so that the covariance LIE E 
decreases to a /e. 
The effect of parameter 8 on the process can be demonstra- 
ted by simulated second order Gauss Markov processes 
(figure 3, figure 4).
