Edit Structural Coefficient

​Context

• BayesiaLab utilizes proprietary score-based learning algorithms, which utilize the Minimum Description Length Score (MDL) to measure the quality of candidate networks with respect to the available data.
• In BayesiaLab, the computation of the MDL Score also includes the so-called Structural Coefficient α as a weighting factor for the structural component $DL(B)$.
• Please see Key Concepts: Structural Coefficient for more details.

Usage

There are multiple ways of how you can open the Structural Coefficient window:

• Select Menu > Edit > Edit Structural Coefficient
• Select Graph Panel Context Menu > Structural Coefficient
• If the Structural Coefficient indicator is displayed in the Status Bar, click on the icon .
• In the open Structural Coefficient window
  • Use the slider to select the desired level.
  • Use the up/down buttons to change the display value in 0.05-increments.
  • Type in the desired value.

Workflow Illustration

• To illustrate the usage of the Structural Coefficient and its impact on learning, we utilize an example presented in the webinar, Analyzing Capital Flows of Exchange-Traded Funds.
