Sorry
I'm student in biomedical engineer and i have to solve this formula
for immuno-assay. I need to design a calibration curve
But i don't understand How can i write this formula in R language:
y = a + (c - a) /(1+ e[-b(x-m])
where
x = ln(analyte dose + 1)
y = the optical absorbance data
a =

Andrea, if you only have five data points, it will be very difficult
to
fit all those parameters so they give a unique solution. If
you want to
fit all of your parameters at once, you need
