In branchingprocess: Calculate Outbreak Probabilities for a Branching Process Model

Probability that n initial cases lead to an outbreak that lasts at least g generations of transmission AND has exactly j total cases after generation g

Description

Probability that n initial cases lead to an outbreak that lasts at least g generations of transmission AND has exactly j total cases after generation g

Usage

pSizeAtGen(g, n, j, R, k)

Arguments

g	Number of generations of transmission
n	Number of initial cases
j	Total size of outbreak after generation g
R	Reproduction number: mean of negative binomial offspring distribution
k	Dispersion parameter of negative binomial offspring distribution

Value

The probability of the given outbreak size at the given generation

Examples

#Probability that 10 initial cases leads to an outbreak lasting at least
# 3 transmission generations and is of exact size 30 after 3 generations  
pSizeAtGen(g=3,n=10,j=30,R=2,k=0.5)
