Normalized Parameter Sensitivity

Analysis menu > Parameter Sensitivity

The Normalized Parameter Sensitivity window contains the following elements:

Toolbar

	Zoom In	Clicking in the plot will enlarge the plot representation.
	Zoom Out	Clicking in the plot will reduce the plot representation.
	Pan	Thus, the plot can be shifted within the window.
	Update content of figure	Updates the plot.
	Configure displayed items	Opens the Visible Parameters and Nodes window where you can determine the content of the Normalized Parameter Sensitivity window.

Plot area

This area shows normalized parameter sensitivity.

By default, all nodes are shown on the X axis, and all parameters are shown on the Y axis. A right-click on a parameter or node name removes that parameter/node from its axis. A (left-)click on a parameter/node name removes the other parameters/nodes from their axis. Right- or left-clicking the last parameter/node name on an axis displays all parameters/nodes.

The colors of the plots are used as follows:

dark gray area

maximum gradient regarding one parameter p_j over all training data points
red line

mean gradient regarding one parameter p_j over all training data points

light gray area

mean gradient ± 1 σ regarding one parameter p_j over all training data points

Note
Smaller absolute values indicate less influence of the parameters on a node.
