add_breakpoints

Add breakpoints to certain dates in a data set.

Estimates the time-varying reproduction number, rate of
spread, and doubling time using a renewal equation approach combined
with Bayesian inference via Stan. Supports Gaussian process and
random walk priors for modelling changes in
transmission over time. Accounts for delays between infection and
observation (incubation period, reporting delays), right-truncation
in recent data, day-of-week effects, and observation overdispersion.
Can estimate relationships between primary and secondary outcomes
(e.g., cases to hospitalisations or deaths) and forecast both. Runs
across multiple regions in parallel. Based on
Abbott et al. (2020) <doi:10.12688/wellcomeopenres.16006.1> and
Gostic et al. (2020) <doi:10.1101/2020.06.18.20134858>.

add_breakpoints function

<dl><dt>data</dt>
<dd>A <code>&lt;data.frame&gt;</code> of disease reports (confirm) by date (date).
<code>confirm</code> must be numeric and <code>date</code> must be in date format. Optionally,
<code>data</code> can also have a logical <code>accumulate</code> column which indicates whether
data should be added to the next data point. This is useful when modelling
e.g. weekly incidence data. See also the <code>fill_missing()</code> function which
helps add the <code>accumulate</code> column with the desired properties when dealing
with non-daily data. If any accumulation is done this happens after
truncation as specified by the <code>truncation</code> argument. If all entries
of <code>confirm</code> are missing (<code>NA</code>) the returned estimates will represent the
prior distributions.</dd>
<dt>dates</dt>
<dd>A vector of dates to use as breakpoints.</dd></dl>
