Hill slope graphpad
WebMar 29, 2024 · The Hill's slope refers to the steepness of the curve. It could either be positive or negative. C = Inflection point. The inflection point is defined as the point on the curve where the curvature changes direction or signs. C is the concentration of analyte where y= (D-A)/2. D = Maximum asymptote. WebMethods: Both computer programs use the iterative method to estimate two of the Hill equation parameters (EC50 and the Hill slope), while constraining the values of the other two parameters (the minimum and maximum asymptotes of the response variable) to fit the Hill equation to the data.
