Join Ron Davis for an in-depth discussion in this video Using the Prediction Calculator, part of Excel Data-Mining Fundamentals.
- Alright, now we'll look at the Prediction Calculator.…The Predication Calculator is a form of 'what if'.…So if we just run this down here, and what we want to look…at is Purchased Bike, and we'll change this over to a Yes.…And I'm not printing anything so I just want Spreadsheets.…So I call Run.…Again, it's analyzing the patterns that are in the table,…and it produces these two charts we have down here.…And what this has is this false positive and true positive.…
The impact of us saying that a positive, that is, a certain…factor will cause them to buy a bike and we're wrong,…and we say that has a factor of 10, and then we say a true…positive, the profit from a true positive is 10.…So if you watch this chart over in here and I say my false…positives are really high, I change that over to a 25,…and you can see now it's moved on up, so we want to...…If I move it down to a five then that drops it's header.…
So it depends on how you see the cost…of making incorrect statements is.…And this is the information that it got, all of the…
