f_z_poiss: Compute the probability of observing an outbreak of size z...

In reconhub/branchr: R Estimation from Cluster Sizes

Description

Compute the probability of observing an outbreak of size z given an R<1 and assuming a Poisson offspring distribution

Usage

f_z_poiss(z, s, R)

Arguments

R	is the reproduction number, i.e. the average number of secondary cases due to a single case. This can be any positive number.

Value

The function returns a list including:

• R_eff: the effective reproduction number. Note that if R<1, then R_eff=R.

• alpha given the reproduction number and assuming a Poisson offspring distribution. Note that if R<1, then alpha=0.

• proba_ext: the probability of extinction given alpha. Note that if R<1, then proba_ext=1.
