bootstrap | R Documentation |
This function can be used to bootstrap [incidence2]
objects. Bootstrapping
is done by sampling with replacement the original input dates.

randomise_groups |
Should groups be randomised as well in the resampling procedure; respective group sizes will be preserved, but this can be used to remove any group-specific temporal dynamics. If |
As original data are not stored in incidence2::incidence objects, the bootstrapping is achieved by multinomial sampling of date bins weighted by their relative incidence.
An [incidence2]
