Full_Name: Sophie Smout Version: 1.5.0 OS: windows 2000, pc Submission from: (NULL) (138.251.190.17) I'm finding that nls iterates to the end of its iteration setting and does not jump out to report convergence even when it has clearly converged. It is also mis-reporting the number of iterations completed. These may not be unconnected... This is an example: [note - details of my computer,

I'm having a problem with nls: it iterates the correct number of times according to nls.control, but mis-reports how many iterations have occured! It converges on the correct parameter values, but doesn't stop and report them until it's done all its iterations. Then it reports as an error that it's stopped becaue it's done all its iterations. Not sure what's going on....

I'm trying to fit a model to solve a biological problem. There are multiple independent variables, and also there are multiple responses. Each response is a function of all the independent variables, plus a set of parameters. All the responses depend on the same variables and parameters - just the form of the function changes to define each seperate response. Any ideas how I can fit
