Usage
showEq()
Arguments
Value
The formula of six equations (with abbr.) will be listed on the screen.
Details
In Hill equation with slope parameter $n = 1$, parameter Beta is equivalent to the effect
concentration causing 50Alpha and Beta are the parameters (location and slope, respectively) to be estimated.
