Exploration of Clusters

First, we shall add a few components to the workflow from the previous assignment

• Attach Select Columns to Hierachical clustering.
• Attach Naive Bayesian classifier to Select Columns.
• Attach Nomogram to Naive Bayesian classifier.

Now for some work. We shall first explore properties of one group vs. the rest of the world.

1. Double click the connection between Hierarchical Clustering to Select Columns. Connect Selected Data from clustering to Data in Select Columns.
2. In Select columns, designate Selected as target. With these two steps, you the naive Bayesian classifier will construct a model for distinguishing between selected and unselected countries.
3. In hierarchical clustering, select the cluster with developed countries (the one including the eastern and western Europe and others).
4. Observe the nomogram. (Set Target class to "Yes".) What is typical for these countries?
5. Repeat this exercise for the cluster with African countries.

Next, let us compare different clusters.

1. Double click the connection between Hierarchical Clustering to Select Columns. Connect Data from clustering to Data in Select Columns.
2. In Select columns, designate Cluster as target. With these two steps, you the naive Bayesian classifier will construct a model for distinguishing between the selected clusters.
3. In hierarchical clustering, select two clusters: the predominantly western and predominantly eastern Europen cluster.
4. In the nomogram, select one cluster or the other and observe the differences.
