will suffer a second heart attack, and if so, how confident we are that the prediction will come true.
Switch to the Scoring results tab. We will look first at the meta data (Figure 9-9).

We can see in this figure that RapidMiner has generated three new attributes for us:
confidence(Yes), confidence(No), and prediction(2 nd _Heart_Attack). In our Statistics column, we
find that out of the 690 people represented, we're predicting that 357 will not suffer second heart
attacks, and that 333 will. Sonia's hope is that she can engage these 333, and perhaps some of the
357 with low confidence levels on their 'No' prediction, in programs to improve their health, and
thus their chances of avoiding another heart attack. Let's switch to Data View.
