Direct Effects

This analysis ranks the Driver Nodes by their Direct Effect on the Target Node, i.e., the effect of each node while all other nodes are held fixed. It can differ substantially from the Total Effect, which lets the other nodes respond. The tabular counterpart, with the Direct Effect, Standardized Direct Effect, Contribution, and Elasticity of each node, is the Direct Effects on Target report.

Quadrants

Target Direct Effect Analysis

The contribution values can be shown directly as labels on the corresponding arcs. As above, the contribution is computed for the selected nodes only; selecting a single node would yield a contribution value of 100%.

Target Mean Analysis

The Target Mean Analysis is also extended with the Direct Effects, allowing the Direct Effect Function to be graphed. The Direct Effect is the derivative of the Direct Effect Function computed at the a priori mean value (delta = 0).
