The use of predictive models to aid drug discovery reduces attrition rates and potentially decreases R+D spend. Two areas that have impaired the wide scale deployment of predictive technology are quality assurance for models and complexity of use. PredictionBase suite provides a complete tool set for the development, quality assurance, deployment and use of both new and existing predictive models. IDBS leads the way in quality assurance with the introduction of the model quality calculator that enables users to measure the applicability and suitability of predictive models.
