The main goal of fitting the dose-response curve in many situations is to determine the best-fit value of the EC50, which is the concentration that provokes a ...

If, as is typical, your doses are equally spaced on a LOG scale, then the uncertainty of the IC50 (or EC50) is symmetrical on a LOG scale. In this case, the SE ...

Choose an equation where X is expected to be dose or concentration, and Prism will fit the EC50 or IC50 directly, with standard errors.

First let's look at the variables without a log transform, H + and EC50. Both come pretty close to the definition of a ratio variable.
