I have hunted around but cannot find the command which allows me to specify parameters of a model.
For example, model.m1 <- nls(y ~ alpha * x1/(beta + x1), data = data, start = list(beta = 20, alpha = 120), trace = TRUE) This will estimate the parameters, which allows to investigate the residuals. What I would like to do is fix the parameters to the data that I have estimated elsewhere, to analyse their residuals. For example, model.m2 <- y ~ 80 * x1/30 +x1 ??????
