I have the data: for x: 2, 8, 14, 20, 26, 32, 38, 44, 50, 56, 62, 68, 74, for y: 100, 99, 99, 98, 97, 94, 82, 66, 48, 38, 22, 10, 1. y depends on x by equation: y = 100*exp(b*(1-exp(c*x))/c), where b and c are coefficients. I need to find coefficients in this equation for given data. How can I do that by means of R? Thank you for advance. With regard, Dmitry.
