exponential function

Exponential (power) model

The model function for the exponential model is defined as [REMOVE_ME]$f(d,\theta)=E_0+E_1(exp(d/\delta)-1)f(d,theta)=E0+E1 (exp(d/delta)-1). [REMOVE_ME_2]$

Description

The model function for the exponential model is defined as

exponential(dose, e0, e1, delta)

Arguments

• dose: Dose variable
• e0: Placebo effect
• e1: E1 parameter
• delta: Delta parameter, controlling the convexity of the model.

Details

This model is intended to capture a possible sub-linear or a convex dose-response relationship.

Returns

Response value
