  In this paper, we will study the large scale structure formation using the
gravitational partition function. We will assertively argue that the system of
gravitating galaxies can be analyzed using the Tsallis statistical mechanics.
The divergences in the Tsallis gravitational partition function can be removed
using the mathematical riches of the generalization of the dimensional
regularization (GDR). The finite gravitational partition function thus obtained
will be used to evaluate the thermodynamics of the system of galaxies and thus,
to understand the clustering of galaxies in the universe. The correlation
function which is believed to contain the information of clustering of galaxies
will also be discussed in this formalism.
