Recently, I started a short study on the theory of nearest neighbours
(of differtent colours). Distances between nearest neighbours are
measured to test if a single population is distributed randomly (e.g.
trees in a forrest). I have found something in these books:

*Quantitative Stereology, Ervin E. Underwood, 1970, Addison Wesley
  Publishing Company.
*Stochastic Geometry and its applications, D. Stoyan, Kendall and Mecke,
  1987, John Wiley and Sons. (not a very clear story; distance
  measurement as a stochastic test).
