Parameter Estimation Results

By default, this interface shows the convergence history (left-side chart) and composite scale sensitivity for each calibrated parameter (K and ε multiplying factors). Click the red ‘>>’ (options) button to access settings and additional information. The results from automatic calibration are displayed in the output, including the initial and final calibrated parameters and statistical indicators of the optimization process.

Run-time Message

This is the runtime output from the calibration tool and gives results, summary statistics, as well as being useful for troubleshooting if there are issues with the calibration process.

Chart I Options

The chart to display on the left side in the Parameter Estimation Results window. Use the 'Redraw' button to effect changes
Chart Type (dropdown) - Convergent History (default) shows the error over iterations, Model vs Data shows just the optimal model against the observed data, and Initial Model vs Data shows optimal (blue) and initial (pink) model results against the observed data.
Statistic Type (dropdown) - the dependent parameter displayed in Chart 1 can be the total weighted square residual or the standard deviation for head, concentration, or flux. Note if a type is chosen for a parameter that wasn't calibrated, no results will be displayed.

Chart II Options

The chart to display on the right side in the Parameter Estimation Results window. Use the 'Redraw' button to effect changes.
Chart Type (dropdown) - this gives options to display which parameters being calibrated have the greatest influence on the model results. Choose between options to view composite (CSS) or dimensionless (DSS) scaled sensativity, or parameter correlation coeficients (PCC).
Parameter Type (dropdown) - choose the model output parameter to display (all, conductivity, recharge, or leakance).
