Predictive analytics | ||
Predictive analytics encompasses a variety of statistical techniques that process current and historical data in order to make “predictions†about future events. Such predictions rarely take the form of absolute statements, and are more likely to be expressed as numbers that correspond to the odds of a particular event or behavior taking place in the future. In business, predictive models are often not embedded in operational processes and activated during live transactions. The models process historical and transactional data to identify the risk or opportunity associated with a specific customer or transaction. These analyses weigh the relationship between hundreds of data elements to isolate each customer’s risk or potential, which guides the action on that customer. Predictive analytics is widely used in making customer decisions. One of the most well-known applications is credit scoring, which is used throughout financial services. Scoring models process a customer’s credit history, loan application, customer data, etc., in order to rank-order individuals by their likelihood of making future credit payments on time. Predictive analytics are also used in insurance, telecommunications, retail, travel, healthcare, pharmaceuticals and other fields. Types of predictive analyticsGenerally, predictive analytics is used to mean predictive modelling. However, people are increasingly using the term to describe related analytic disciplines, such as descriptive modeling and decision modeling or optimization. These disciplines also involve rigorous data analysis, and are widely used in business for segmentation and decision making, but have different purposes and the statistical techniques underlying them vary. Predictive models Predictive models analyze past performance to assess how likely a customer is to exhibit a specific behavior in the future. This category also encompasses models that seek out subtle data patterns to answer questions about customer performance, such as fraud detection models. Predictive models often perform calculations during live transactions, for example, to evaluate the risk or opportunity of a given customer or transaction, in order to guide a decision. Descriptive models Descriptive models “describe†relationships in data in a way that is often used to classify customers or prospects into groups. Unlike predictive models that focus on predicting a single customer behavior (such as credit risk), descriptive models identify many different relationships between customers or products. But the descriptive models do not rank-order customers by their likelihood of taking a particular action the way predictive models do. Descriptive models are often used “offline,†for example, to categorize customers by their product preferences and life stage. Decision models Decision models describe the relationship between all the elements of a decision — the known data (including results of predictive models), the decision and the forecast results of the decision — in order to predict the results of decisions involving many variables. These models can be used in optimization, a data-driven approach to improving decision logic that involves maximizing certain outcomes while minimizing others. Decision models are generally used offline, to develop decision logic or a set of business rules that will produce the desired action for every customer or circumstance.
