Interactions <output>
Model menu > Interactions ><output>
The degree of interaction of two inputs on the respective output is graphically displayed in this window.
In every individual diagram, an input variable (the column) is continuously being varied, a second input variable (the row) features three discrete values Min, Mean and Max, which results in three graphs per diagram.
A significant interaction between two inputs each is present if the graphs in a diagram do not run parallel or even intersect.
Example
In Diagram 1, the variable ex_cam continuously varies, while ignition is represented with three different values (-6.2, -2.03656 and 2.3). Since all three graphs run parallel to each other, it follows that only a minor interaction is present between both inputs.
A different scenario in Diagram 2: Here, the continuous variation of injection at three different values of load leads to cross-overs so that a significant interaction between both inputs can be assumed in this case.

The values of the inputs are displayed by the dashed blue line and can be set here just like in the ISP view. |
