Ssurveys

<p>Count data from six different surveys looking at the number of sources/groups

public.</p>

datasets

Fits Zeta distributions (discrete power laws) to data that arises
from forensic surveys of clothing on the presence of glass and paint in
various populations. The general method is described to some extent in
Coulson, S.A., Buckleton, J.S., Gummer, A.B., and Triggs, C.M. (2001)
<doi:10.1016/S1355-0306(01)71847-3>, although the implementation differs.
