Undirected Graphs When the Causality Is Mutual
Structural equation models impose causal order on a set of observations. We start with a measurement model: a list of theoretical constructs and a table assigning what is observed (manifest) to what is hidden (latent). Although it is possible to think of this assignment as formative rather than reflective, the default is a causal conn...

The Graphical Network Associated with Customer Churn
The node representing “Will Not Stay” draws our focus toward the left side of the following undirected graph. Customers of a health care insurance provider were asked about their intentions to renew at the next sign-up period. We focus on those indicating the greatest potential for defection by creating a binary indicator separating those who...

The Network Underlying Consumer Perceptions of the European Car Market
The nodes have been assigned a color by the author so that the underlying distinctions are more pronounced. Cars that are perceived as Economical (in aquamarine) are not seen as Sporty or Powerful (in cyan). The red edges connecting these attributes indicate negative relationships. Similarly, a Practical car (in light goldenrod) is not Technicall...

Graphical Modeling Mimics Selective Attention: Customer Satisfaction Ratings
As shown by the eye tracking lines and circles, there is more on the above screenshot than we can process simultaneously. Visual perception takes time, and we must track where the eye focuses by recording sequence and duration. The “50% off” and the menu items seems to draw the most attention, suggesting that the viewers were not men.But wh...

Clustering Customer Satisfaction Ratings
We run our cluster analysis with great expectations, hoping to uncover diverse segments with contrasting likes and dislikes of the brands they use. Instead, too often, our K-means analysis returns the above graph of parallel lines indicating that the pattern of high and low ratings are the same for everyone but at different overall levels. The da...

Mutually Exclusive Clusters Are Boxes within Which Consumers No Longer Fit
Sometimes we force our categories to be mutually exclusive and exhaustive even as the boundaries are blurring rapidly.Of course, I am speaking of cluster analysis and whether it makes sense to force everyone into one and only one of a set of discrete boxes. Diversity is diverse and requires a more expressive representation than possib...
