Description

This is the core function of the generalized logistic analysis used in genlog.

Usage

1
genlogFunction(x, x0, Ab, At, B, v)

Arguments

x

A numeric vector with measurement moments or indices of measurement moments.

x0

A single numeric value specifying at which moment the curve is at its midpoint (when v = 1).

Ab, At

Respectively the lowest and highest possible values of the dependent variable.

B

The growth rate (curve steepness).

v

Um - Peter, wat is 'v' eigenlijk?
