Psurveys

<p>Count data from six different surveys looking at the number of sources/groups
of glass found on the upper surfaces of clothing taken from the general 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.

Fit Zeta Distributions to Forensic Data

Psurveys function

<p>A <code>list</code> with nine objects of class <code>psData</code>---see
  <code>readData</code> for more details. The elements of the list are
  named: <code>coulson</code>, <code>jackson</code>, <code>lau</code>, <code>lewis.all</code>,
  <code>lewis.clothing</code>, <code>lewis.shoes</code>, <code>pettard</code>,
  <code>ross</code>, and <code>roux</code>, corresponding to the lead author in each of
  the references given below. <code>lau</code>, <code>pettard</code>, and <code>ross</code>
  were taken from Coulson et al. (2001) rather than the original source. The three
  objects starting with <code>lewis</code> represent the combined data (<code>all</code>),
  the groups of glass found on the outer clothing (<code>clothing</code>), and the groups of
  glass found on shoes/footwear (<code>shoes</code>).</p>
