Density density correlation function
WebThe probability density function (" p.d.f. ") of a continuous random variable X with support S is an integrable function f ( x) satisfying the following: f ( x) is positive everywhere in the support S, that is, f ( x) > 0, for all x in S. … WebThe pair correlation function g(r) accounts for these factors by normalizing by the density; thus at large values of r it goes to 1, uniform probability. The right picture above shows …
