Logarithmic dose–response curves are generally sigmoidal and monotonic and can be fit to a classical Hill equation. The Hill equation is a logistic function with respect to the logarithm of the dose and is similar to a logit model. A generalized model for multiphasic cases has also been suggested. philly cheesesteak adventure
