poisson_relrisk

<p>A <code>data.table</code> with columns <code>zone, duration, count,
mu</code>. The latter two are the sums of observed counts and estimated expected
value parameters for the locations comprising the zone and up to the given 
duration (i.e. cumulative sum for the duration).</p>

table

<p>This function adds a column for the maximum likelihood estimate for the
relative risk (assumed to be 1 or greater). The table should contain the
aggregates (sums) of the counts and expected value parameters for each zone 
and duration.</p>

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.

poisson_relrisk: Add column for relative risk MLE to table with aggregate counts and means.
