Berkshire uses assumptions derived from its collateral database for internal modeling purposes and for completing predictive modeling assignments. Some clients prefer to conduct custom searches and analysis independently using our powerful online tools and datasets. We offer that flexibility, and we offer data hosting and analysis as a subscription service to those clients. For expert insights, customized solutions, and deeper analytics, Berkshire also provides full-service consulting through our Predictive Modeling offering.
