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

Description

The derivative of the generating function of the branching process f(s) = ∑_k p_k s^k.

Usage

derivative_generating_function(s, a = 10, b = 1, lambda = 0.11, p = 0.5)

Arguments

s	The argument of the generating function. 0<s<1.
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 derivative of the generating function at s.
