Logistic: Logistic function

In IMPRESSPROJECT/ModelingPopulation: Modeling of an exploited population (structured by age)

Description

Computes the logistic function.

Usage

Logistic(x, x50, xd)

Arguments

x	Points where the logistic function must be computed.
x50	x-value of the sigmoid's midpoint of the logistic function.
xd	Minus the inverse of the logistic growth rate (steepness of the curve).

Details

The function implements the logistic function which equation is

L(x)=1/(1+exp((x-x50)/xd))

where x50 is the x-value of the sigmoid's midpoint of the logistic function, and xd is minus the inverse of the logistic growth rate (steepness of the curve).

Value

Vector containing the values of the logistic function in each of the x-values.
