As a user of Predictive Analysis I thought that I would share this hidden gem, inside the Expert Analytics option – the ability to do further analysis and create visualisations on the results of your predictive models.

Let me show you an example of what I mean by this.

Below is a screenshot of a cluster analysis that I have created inside the Predict tab of Expert Analytics.

Looking at the results I can see how the clusters are represented using the standard visuals that are available for cluster analysis.

This is great, however what I also want to do is analyse the clusters themselves and look at the data in more detail: i.e. use the visualise panel to create different visuals to understand what data makes up each cluster and filter on clusters to analyse further.

You can do this however it is not very obvious.  To do this follow these steps:

1. After you have created and run your predictive model click on the Visualise tab.

2. Just below the Visualise tab there is a “Select Component” drop down option

3. Notice that I can select “Auto Clustering” – this is the results set of the clustering that I have just performed in the Predict tab.

4. Select this.

Now I can create new visuals.  The data includes the extra predictive column created through my predictive model.  This enables me to filter on specific clusters and analyse further what makes up these clusters.

You can do this on any predictive model results set, making further analysis of the results of your models very easy to do.

Hope that this helps in your work.
