Significance of the Clustering Parameter and its Relation to Galaxy Clustering

Various issues pertaining to the clustering parameter in relation to galaxy clustering are outlined. Its evolution from an ``Educated Guess'' introduced in the Gravitational Quasi-Equilibrium Distribution theory to the establishment of a rigorous mathematical basis is explained. An attempt is made to give an idea of the importance of the clustering parameter without getting lost in the galaxy distribution function discussed in detail in our previous works. Spatial galaxy distribution function is outlined only in the context of the role of the clustering parameter.
