BayesiaLab Webinar Series

Analyzing the 2016 General Social Survey with BayesiaLab's Unsupervised Learning Algorithms

Recorded on February 16, 2018

 

Webinar Materials

Abstract

In this webinar, we explore the high-dimensional relationships between hundreds of variables from the 2016 General Social Survey.[1] Our objective is to employ one of BayesiaLab's Unsupervised Learning algorithms to generate a Bayesian network model that approximates the joint probability distribution of the underlying survey responses. 

Once we have this representation, we can address research questions that specifically require computing the joint probability. In this context, a prototypical—albeit theoretical—issue would be how to best approximate the diversity of many voters through a small number of elected representatives. This translates directly into a variable and data clustering task, which will be at the core of our presentation. Our objective will be to trade off the faithfulness of voter representation with the number of variable/data clusters to be generated.

Workflow to be presented in the webinar:

  • Transform original GSS data in SPSS format with Stat/Transfer 14.
  • Import data, variables labels, and value labels into BayesiaLab.
  • Define variable classes, e.g., demographics, voting behavior, etc.
  • Perform Unsupervised Learning.
  • Optimize Bayesian network model with Structural Coefficient Analysis.
  • Identify Latent Factors through BayesiaLab's Variable Clustering.
  • Cluster voters into segments with Data Clustering (Multi-Net).
