The applied weighting is used to offset heteroscedasticity by taking into account the change in variance which occurs with an increase in signal. All samples are first corrected by the mean of the blank group measurements.

The standard dose-response curve is sometimes called the four-parameter logistic equation. It fits four parameters: the bottom and top plateaus of the curve, the EC50 (or IC50), and the slope factor (Hill slope). This curve is symmetrical around its midpoint. To extend the model to handle curves that are not … See more Create an XY data table. Enter the logarithm of the concentration of the agonist into X. Enter response into Y in any convenient units. From the data table, click Analyze, choose nonlinear regression, and … See more LogXb = LogEC50 + (1/HillSlope)*Log((2^(1/S))-1) Numerator = Top - Bottom Denominator = (1+10^((LogXb-X)*HillSlope))^S … See more •If your goal is to obtain meaningful best-fit parameters, then you'll need lots of high quality data. It is very hard to fit both slope and asymmetry with tight confidence intervals. If your goal is just to interpolate unknowns from a … See more Bottomand Topare the plateaus at the left and right ends of the curve, in the same units as Y.
