Hello everyone,

 

I would like to ask 2 questions about Visual Statistics:

1)What do exactly interaction variables  show?

2)If a Cluster ID is used in another model and improves it, does it mean that Clustering has been efficient?

"Interaction" in SAS Visual Statistics simply means an interaction effect. https://en.wikipedia.org/wiki/Interaction_(statistics)

 

you can create an interaction interaction and apply in a regression models such as linear regression, logistic regression, and generalized linear models.

 

"cluster ID" is the segmentation you can derived based on a Visual Statistics clustering model - this new column is created on the fly and can be used in another Visual Statistics model or Visual Analytics graph. Whether it is efficient is really up to your assessment based on the clustering outputs. 🙂
