Derived Parameter Expression

What is it?

To indirectly calibrate a model parameter to a dataset, or calibrate correlated parameters, a parameter expression can be used to translate between the two.

How to use it:

1) Select the appropriate anchor parameter
2) Enter the relationship between the derived and anchor parameters. For example, if calibrating parameters A and B and A = 3B, then set A as a derived parameter, B as an anchor parameter, and enter the relationship 3 * [B].
3) Click 'OK' to save and close, or 'Cancel' to exit window without saving parameter expression.
