Predictive Trees

Predictive Trees are created by selecting Insert > Analysis > Predictive Tree.

tutorial video is available as well as a walkthrough on our blog.

A predictive tree shows the relationship between some target data and some other data (selected when pressing Insert > Analysis > Predictive Tree). The target data is described in each of the boxes (called nodes).  The node shown at the 'top' of the upside-down tree shows the results for all the data. In this example, it shows that the target data is called Estimated profit to the industry and its average value is $6,192.

Each of the boxes shown underneath the tree is a segment of people from the database that have been found to be different in terms of their profit and related data.  Reading from the left to right we can see that:
  • If the people are working in a company with 48 or more employees which is in agriculture, forestry, fishing, communications services, transport or storage, their average profitability was around $61,000, which is roughly ten times the average for the total database.  Thus, this segment should likely be targeted.  However, note that it only accounts for 1% of the database.
  • Where there are 48 or more employees in one of the other industries, the profit drops to $18,621, which is a lot lower than the first segment but is still triple the average, suggesting that obtaining such firms as new customers is likely to be desirable (i.e., this is a prediction that comes from this analysis).
  • Where the number of employees is not known (i.e., 'Missing data'), or between 10 and 24, the average profit is $6,255.40.
  • Etc.
