Daily incidence implied by a growth curve

For a cumulative growth curve \(C(u)\) with \(C(0)=y_0\), returns the expected count in each unit interval, \(\mu_u = C(u) - C(u-1)\), \(u = 1, 2, \ldots\).

Usage

growth_incidence(u, model, y0, K, gamma, beta = 1.5)

Arguments

u

Integer local times (1 = first day of the segment).

model

One of "logistic", "gompertz", "richards".

y0, K, gamma

Curve parameters (0 < y0 < K, gamma > 0).

beta

Richards shape parameter.
