# Features of IBM SPSS Statistics

## IBM SPSS Statistics - Functions and services of the SPSS modules

The IBM SPSS Predictive Analytics software supports companies with all kinds of predictions and analyzes in order to be able to identify potential problems more easily. The planning process, which has been improved with detailed forecasts and analyzes from SPSS, enables more precise decisions to be made in the company and thus better business results to be achieved. The differentiation between the functions and forecast models contained in the individual modules is not always easy. In our overview we show which functions and features the individual modules of the IBM SPSS Statistics products contain.
