New clients often have questions about why and how frequently CAN needs to update their predictive models. Predictive models need to be updated because everyday new data is being created. For example, your customers are buying more, subscribing or unsubscribing. The environment is constantly changing. While predictive models can handle a lot of new new data, overtime environmental changes build up causing predictive models to lose their effectiveness. After a month, quarter, or a year it is necessary to update predictive models with new data.
