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

genlog

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

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

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

v

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

The growth rate (curve steepness).

Um - Peter, wat is 'v' eigenlijk?
