How to compare parameters of non linear fitting curves
Hi, I'm using a non linear model to fit experimental survival curves. This model describes the fraction of "still active" experiments as a function of time t as follows: f(t)=(1+exp(-etaD*cD)) / (1+exp(etaD(t-cD))) Moreover, when experiments are still active, they may change of state (from 0 to 1). But they may fall inactive before changing their state (their state still equals 0). The survival curve of state may also be fitted with the following model: f(A)=(1+exp(-eta1*c1))...
