- Grouping predictors
Group predictors in the Model development step to prepare reliable models. The process of model development has three default models: regression, decision tree, and bivariate. A common setting that applies to all types of models is the selection of the predictors.
- Creating models
In the Model creation step, you get sample models: one default regression model, one default decision tree model, and optionally by a benchmark model or models. During modeling, you can add more models and save them. A good practice is to create each type of model and compare their key characteristics.
- Benchmark models
A benchmark model appears unavailable in the Model creation step when you define a benchmark role for a field during the Analyzing data step.
- Sensitivity of models
Model sensitivity is the correlation between the behavior predicted by the predictive model and the behavior predicted by one of its predictors.
