The sensitivity function indicates whether or not the model solution is sensitive to the parameter over the range of the independent variable. If the value of p is 0, the sensitivity function cannot be calculated. The sensitivity functions are not calculated until they are plotted. During a sensitivity run clicking the cancel button cancels the run. Plotting the results of sensitivity runs is discussed in section 8.6.4 .
Residuals Clicking the residuals button causes a residuals run to be initiated.
The residuals button becomes operable when a model and TAC file have been successfully loaded. Successful initiation of a residuals run requires that the Residuals Configuration dialogue window be filled in, see section 8.2.6 . The estimated solution is obtained by linear interpolation of the model output curve at the values of the independent variable of the data curve. The weight function can be obtained in several ways described in section 8.2.4 . During a residual clicking the cancel button cancels the run .
