i2extras adds additional functionality to the incidence2 package.
The main features of the package include:
fit_curve() and growth_rate(): fit a
trend (poisson / negative binomial) to an incidence2 object
and calculate the associated growth rate.
add_rolling_average(): add a rolling average to an
incidence2 object.
bootstrap(): generates a bootstrapped
incidence2 object by re-sampling, with replacement, the
original dates of events.
find_peak(): locates the peak time of the
epicurve.
estimate_peak(): uses bootstrap to estimate the peak
time (and related confidence interval) of a partially observed
outbreak.
