Boltzmann sigmoidal curve fitting. This variable is called the Hill slope, the slope factor, or the Hill coefficient. After fitting the parameters of a sigmoidal function to the data, the graph’s characteristics represent a rather comprehensive quantitative reflex description. Curve Fitting Toolbox™ supports logistic, 4-parameter logistic, and Gompertz sigmoidal models with the following equations. With different kinds of variables, this variable is sometimes called ED50 (effective dose, 50%), or IC50 (inhibitory concentration, 50%, used when the curve goes downhill). 16 Boltzmann Function Brief Description Boltzmann Function - produce a sigmoidal curve. . Note that coefficient bounds are overridden by holding a coefficient constant. Variants of the 4-parameter Boltzmann sigmoidal equation are widely used for curve fitting. •HillSlope describes the steepness of the curve.
