Providing the mean function and the corresponding self starter function for the asymptotic regression model.
meAR.2(x, d, e) meAR.3(x, c, d, e)
| x | numeric vector specifying the dose |
|---|---|
| d | upper limit |
| e | \(e>0\) is determining the steepness of the increase as \(x\) |
| c | lower limit at at \(x=0\) |
The asymptotic regression model is a three-parameter model with mean function: $$ f(x) = c + (d-c)(1-\exp(-x/e))$$ The parameter \(c\) is the lower limit (at \(x=0\)), the parameter \(d\) is the upper limit and the parameter \(e>0\) is determining the steepness of the increase as \(x\).
