Package: ptools Title: Tools for Poisson Data Version: 2.0.0 Authors@R: person(given = "Andrew", family = "Wheeler", role = c("aut", "cre"), email = "apwheele@gmail.com", comment = c(ORCID = "0000-0003-2255-1316")) Maintainer: Andrew Wheeler Description: Functions used for analyzing count data, mostly crime counts. Includes checking difference in two Poisson counts (e-test), checking the fit for a Poisson distribution, small sample tests for counts in bins, Weighted Displacement Difference test (Wheeler and Ratcliffe, 2018) , to evaluate crime changes over time in treated/control areas. Additionally includes functions for aggregating spatial data and spatial feature engineering.
