Use this command to apply a model to the analysis data with current scaling and range positions,. This performs a non-linear least squares analysis of the data.
If you use Automatic Analysis, you will not need to use this command. It is done for you.
Use this command after you have opened a data file, chosen a model, and positioned the model's ranges. If you change the model using the Quick Model Editor, the Full Model Editor, or by positioning ranges, you need to use this command to re-fit the data with the model.
