In reconhub/i2extras: Functions to Work with 'incidence2' Objects

Scope

i2extras adds additional functionality to the incidence2 package.

What does it do?

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.

Installing the package
