Defines the gamma functions in terms of the mean reproductive number (R) and the dispersion parameter (k)

• dgammaRk() for the gamma density function

• pgammaRk() for the gamma distribution function

• fvx() fore the gamma probability density function (pdf) describing the individual reproductive number \(\nu\) given R0 and k

Usage

dgammaRk(x, R, k)

pgammaRk(x, R, k)

fvx(x, R, k)

Arguments

R

A number specifying the \(R\) parameter (i.e. average secondary cases per infectious individual).

k

A number specifying the \(k\) parameter (i.e. dispersion in offspring distribution from fitted negative binomial).
