  How to use it: 
  Ordinal variables can be used in SAP Predictive Analytics to create predictive models. They can be used to identify patterns and trends in data, and to make predictions about future outcomes. For example, an ordinal variable could be used to predict customer satisfaction ratings based on past survey responses. 
  
  Tips & Tricks: 
  When using ordinal variables in SAP Predictive Analytics, it is important to ensure that the data is properly encoded. This means that the values should be assigned numerical values that accurately reflect their order. For example, if the values are low, medium, and high, they should be encoded as 1, 2, and 3 respectively. 
  
  Related Information: 
  Ordinal variables are just one type of data that can be used in SAP Predictive Analytics. Other types of data include nominal variables (which have no natural ordering) and continuous variables (which have an infinite number of possible values). Understanding how to use each type of data correctly is essential for creating accurate predictive models.
