using R software to fit nonlinear regression: sslogist and ssGompertz and SSweibull' functions , For the three functions, use the self-starting R methods and report the data and the three fitted lines - all on the same plot for comparisonreasons, the confidence intervals of parameters and tests indicating if any of them is zero, predict values residual plots and diagnostics, methods to identify which of the threemodelsis betterfit e.g. based on RMSE.
