As you begin working with the prediction wizard, it's important to bear in mind the differences between a wizard template and a predictive model. A simple analogy might be the distinction between a cake recipe and a baked cake. The wizard template is like a cake recipe which can be changed and edited at any time. The predictive model is more like an actual cake which cannot be remade after you remove it from the oven. If the cake is not tasty, you need to fix your recipe and bake a new one.
- A wizard template is used to record the various selections you make in the wizard dialogs.
- A wizard template can be saved and then reloaded at a later time in order to preserve the selections that you make in the wizard dialogs.
- A wizard template can have multiple versions with the same name.
- A wizard template can be used with any report that is based on the same data model.
- A predictive model can be trained on small sub-sets of data and run on a full data set.
- Once a predictive model is created, it can be run "as is" but cannot be edited.
- Each predictive model has a unique name. You cannot create multiple versions with the same name.
- A predictive model can be used with any report that is based on the same data model. It can also be used with a report based on a different data model, provided the model contains the EXACT same element names on which the predictive model is based (dimension, hierarchies, measures, etc.).
