 <h2>DESCRIPTION</h2>
 
+<em>v.nnstat</em> indicates clusters, separations or random distribution of point dataset in 2D or 3D space using Nearest Neighbour Analysis. The method is based on comparison of observed average distance between the nearest neighbours and the distance which would be expected if points in the dataset are distributed randomly. More detailed information about theoretical background is provided in (<a href="https://courses.washington.edu/bio480/Week1-PAPER-Clark_and_Evans1954.pdf">Clark and Evans, 1954</a>), (<a href="http://journals.aps.org/rmp/pdf/10.1103/RevModPhys.15.1">Chandrasekhar, 1943, p. 86-87</a>). Details about the module and testing are summarized in (<a href="http://geoinformatics.fsv.cvut.cz/pdf/geoinformatics-fce-ctu-2013-11.pdf">Stopkova, 2013</a>).
