<p>The big data.frame from the `zinb_analysis_tool` function</p>

big_data

<p>This function is a visualization tool of group level RRs
obtained from the `zinb_analysis_tool`. It will generate a
heatmap with each cell representing the
RR of an AE group with a vaccine.</p>

The method zGPS.AO (Zero Inflated Gamma Poisson Shrinker with AE
(Adverse Event) ontology) is based on the zero-inflated negative binomial
distribution.
It estimates the association between a specific vaccine and an adverse event
group, as well as associations between that vaccine and individual adverse
events within the adverse event group. This model handles the adverse event
count data with excess zeros and over-dispersion, and it allows borrowing
information from adverse event data in the same group. Details can be found
in  "Data Mining in Large Frequency Tables With Ontology, with an Application
to the Vaccine Adverse Event Reporting System."
