Non Linear, Regression, R, Modelling.
mod1 <- nls2(formulaExp, data=datasub, start = grid.theo, algorithm = "brute-force") plot(mod1) nls2(formulaExp, data=datasub, start = mod1) I am getting a lot of errors. However, the model does produce. You can see the formula, the coefficients, and the residual sum of squares of the model chosen.
