The initial Nonlinear Fit report includes the following items, shown in Initial Nonlinear Fit Report.

Shows a plot of the X and Y variables for models with only one X variable. The model based on the current values is shown on the plot. To change the current values of the parameters, use the sliders or edit boxes beneath the plot.

After you click Go to fit a model, the report includes the following additional items, shown in Fitted Model Report.

Computes confidence intervals for all parameters. The intervals are profile likelihood confidence intervals, and are shown in the Solution report. The confidence limit computations involve a new set of iterations for each limit of each parameter, and the iterations often do not find the limits successfully. The Edit Alpha and Convergence Criterion options are for the confidence interval computations For details about the Goal SSE for CL, see Profile Likelihood Confidence Limits.

Shows the confidence limits for the parameters. They are missing until you click the Confidence Limits on the Control Panel. For more details about the confidence intervals, see Profile Likelihood Confidence Limits.
