meL: The logistic model

In DoseResponse/medrc: Mixed effect dose-response curves

Description

The general asymmetric five-parameter logistic model for describing dose-response relationships.

Usage

meL.2(x, b, e)

meL.3(x, b, d, e)

meL.4(x, b, c, d, e)

meL.5(x, b, c, d, e, f)

Arguments

x	numeric dose vector.
b	steepness
e	ED50
d	upper limit
c	lower limit
f	asymmetry

Details

The default arguments yields the five-parameter logistic mean function given by the expression

f(x) = c + \frac{d-c}{(1+\exp(b(x - e)))^f}

The model is sometimes referred to as the Boltzmann model.
