What is Predictive Analytics?

Predictive analytics is the study of historical and current data to make future predictions. It uses a mixture of advanced mathematical, statistical, and machine learning techniques to analyze data to determine and extrapolate hidden trends.  \n

Many businesses and organizations use predictive analytics to guide future decisions. For example, marketing analysts use predictive analytics to determine future sales for their products, weather stations use it to forecast weather, and stockbrokers use it to maximize trading returns.","id":"seo-faq-pairs#what-is-predictive-analytics","customSort":"1"},"metadata":{"tags":[{"id":"seo-faq-pairs#faq-collections#predictive-analytics","name":"predictive-analytics","namespaceId":"seo-faq-pairs#faq-collections","description":"

  Predictive analytics today is largely based on advanced machine learning techniques. Data scientists use deep learning and complex algorithms to analyze multiple variables to create predictive models able to forecast likely behavior from big data.  \n

  As with many machine learning applications, predictive analytics is a dynamic activity that’s constantly using new data to update predictions. This means the technique uses the classic machine tool pipeline of data cleansing, model training, deployment, feedback, retraining, and redeployment together with an ability to ingest data in close to real time. Techniques include decision trees, regression analysis, time series analysis, and deep learning neural networks.  \n

  Predictive analytic models that guide future business decisions tend to be complex and involve taking numerous factors into account. These generally take time to develop and validate and need continual returning to adapt to changes in the business and economic environment. ","id":"seo-faq-pairs#how-pred-analysis-works","customSort":"4"},"metadata":{"tags":[{"id":"seo-faq-pairs#faq-collections#predictive-analytics","name":"predictive-analytics","namespaceId":"seo-faq-pairs#faq-collections","description":"

  Many organizations actively use predictive analytics to guide real-time and future decision-making. \n

  Finance \n

  The financial sector uses predictive analytics to guide decision-making. Examples include predictive market trading, credit risk assessment, and loan approvals. Insurance companies use predictive analytics to predict extreme weather events to mitigate insurance claims and detect fraudulent insurance claims. \n

  Retail \n

  Retail companies use predictive analytics to forecast regional and local customer demand and pre-deliver stock to regional and local distribution stations to reduce delivery times. Other companies use lead scoring models to improve lead conversion rates as well as predictive recommendations to increase up- and cross-selling opportunities based on customer profiles. Companies also use predictive analytics to forecast future demand and sales. \n

  Manufacturing \n

  Manufacturers use predictive analytics to monitor production line equipment to optimize throughput, detect irregularities, and highlight equipment defects. Manufacturing companies use predictive analytics to monitor machinery, identify machine conditions, and predict maintenance requirements. \n

  Healthcare \n

  Healthcare companies use predictive analytics on patient monitoring equipment to detect real-time changes in patients' conditions while largely eliminating spurious alarms that render patient monitoring equipment ineffective. Other use cases include medical diagnosis and predicting the course of a disease based on past data and the patient's health.","id":"seo-faq-pairs#predictive-analytics-use-cases","customSort":"5"},"metadata":{"tags":[{"id":"seo-faq-pairs#faq-collections#predictive-analytics","name":"predictive-analytics","namespaceId":"seo-faq-pairs#faq-collections","description":"
