Apparent independency of an aggregation system with injection

Abstract
We investigate the spatial correlation of a model of aggregation system with injection. This system is characterized by a single point on the f-α diagram (f=1,α=3) which is identical to the case of independent power-law distributions. The R/S analysis also shows no dependency. However, theoretically there exists a higher-order correlation which is difficult to detect but strong eneough to modify the exponent of mass distribution.
