char_function: The characteristic function of the branching process.

In pspc-data-science/branchsim: Gamma negative binomial branching process simulation of epidemics

Description

The characteristic function of the branching process.

Usage

char_function(u, a = 10, b = 1, lambda = 0.11, p = 0.5)

Arguments

u	The argument of the geberating function.
a	The shape parameter of the gamma life time distribution. Default a =10
b	The rate parameter of the gamma life time distribution. Default b = 1
lambda	The arrival rate of infectious interactions. Default lambda = .11
p	The parameter of the logarithmic distribution for the number of infected during an event. Default p=0.5

Value

The evaluation the characteristic function at u.
