Graphpad four parameters

WebJan 1, 2015 · Discussion. The four-parameter logistic equation, also known as the Hill equation (Eq. (1)) is commonly used to model the non-linear relationship typically seen in the association between dose and response. This involves the estimation of four parameters ( a – d) in the equation.
