net.simplace.simulation.control.selectors.LeastDifferenceSelector

Configuration

The user has to specify

• the error method cMode
• the two variables, that will be compared (normally observed and simulated data) as cObserved1 and cSimulated1
• the frequency at which the selector compares the values

Configuration in project file is given as

| 	<selector id="LeastDifference" class="net.simplace.simulation.control.selectors.LeastDifferenceSelector" frequence="YEARLY" >
| 		<input id="cMode">RRMSE</input>
| 		<input id="cObserved1" mode="MAX" source="data.obs"/>
| 		<input id="cSimulated1" mode="MAX" source="model.sim"/>
| 	</selector>

Output

• id of selected simulation as a one size CHARARRAY selectecsimulations
• error of selected simulation ErrorValue
• errors of all simulations ErrorValues as DOUBLEARRAY
• the error method ErrorMethod used

Notice

This generator uses the WeightedLeastDifferenceSelector with only one variable and weight 1 to calculate errors and select the simulation.

Error methods

• Bias - mean error
• SignedBias - mean error, selects the smallest signed bias
• MRE - mean relative error
• MAE - mean absolute error
• RMAE - relative mean absolute error
• MSE - mean squared error
• RMSE - root mean squared error
• RRMSE - relative root mean squared error
• SMAPE - symmetric mean absolute percentage error
• EF - model efficiency
• r - Correlation Coefficient
• rc - Concordance Correlation Coefficient
• index - Agreement Index
• NONE - Void Error Calculator
