Stan Code for the Sigmoid Model.

Stan Code for the Sigmoid Model.

Usage

sigmoid_stanvar()

Note

stanvar script of a sigmoid dose response equation. For log dose greater than negative infinity (dose greater than 0), the sigmoid dose response equation is used. ac50 is the half maximal response, hill is the slope, top is the maximum response, and bottom is the minimum response. For log dose equal to negative infinity (dose equal to 0), if hill is positive, then the bottom value is returned. If hill is negative, then the top value is returned.
