zip_calculations

A <code>data.table</code> with columns <code>location, duration, mu,
p, count</code>. The column <code>mu</code> contains the Poisson expected value 
parameters, the column <code>p</code> contains the excess zero probabilities.

table

A <code>set</code> of zones, each zone itself being a <code>set</code>
containing locations. Locations should be encoded as integers.

zones

Arguments passed to <code><a rd-options="" href="/link/simulate_zip_scanstatistic?package=scanstatistics&version=0.1.0" data-mini-rdoc="scanstatistics::simulate_zip_scanstatistic">simulate_zip_scanstatistic</a></code>.

Calculate the logarithm of the ZIP statistic for each space-time window, 
summing over the locations and times in the window.

internal

Detection of anomalous space-time clusters using the scan
statistics methodology. Focuses on prospective surveillance of data streams,
scanning for clusters with ongoing anomalies. Hypothesis testing is made
possible by the generation of Monte Carlo p-values.
