\title{Linear-logistic function}
\description{
  Helper function describing a special type of dose-response curves, showing a stimulus
  at subtoxic doses.
}
\usage{

  \item{f}{
    One of the parameters describing the curve shape.}
  \item{mu}{
    The parameter describing the location of the curve (log EC50).}
  \item{b}{
    One of the parameters describing the curve shape.}
