stable_convolve

Unlike <code><a href="/link/stats%3A%3Aconvolve()?package=EpiNow2&version=1.8.0" data-mini-rdoc="EpiNow2::stats::convolve()">stats::convolve()</a></code>, this function does not use the FFT algorithm,
which can generate negative numbers when below machine precision.

internal

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>.
