Learning about Automated Clustering with SAP Predictive Analytics 2.0
I watched this video to get started with SAP Predictive Analytics:
I was interested in the automated clustering; you can do clustering analysis with the Expert Analytics part of Predictive but this time, I thought, why not let the tool “do it for me”?
First (and this took the longest time) when I selected type “Excel” it is looking for an .XLS file, not XLSX
So I found a sample file that was .XLS
Figure 2 shows you can upload a description file (field names and lengths) – I just went with “Analyze” and fortunately it read the headings and length of the first row of the Excel file.
Figure 3 shows the results of Analyzing
I didn’t select any target variables or weighted variables. I select 5 (minimum) to 10 (maximum) clusters
The above shows the results and decides that 5 clusters is “winner”.
Figure 6 shows the cluster frequencies
Figure 7 shows another cluster frequencies report that is available
Figure 8 is a bubble chart offered. What could you do with this? Possibly if you are a US tax service, you could offer your tax counseling advice to those at age 42 with high capital gains.
Once I got past the confusion of analyzing the descriptions and to use an old version of Excel, this tool was very simple to use; simply load a file and start analyzing.
