You can use the new Forecasting capabilities in Cognos Analytics to discover and model, trend, seasonality, and time dependence in data.
You can forecast by using automated tools that model time-dependent data. Automated model selection and tuning makes forecasting easy to use, even if you are not familiar with time series modeling.
For the dashboard user evaluating time series data a forecast button will appear in Line and Column visualizations, which when toggled will allow users to see future predicted values with seasonality also evaluated.
