Data Science in SAS ( Explore Predictive Modelling and Machine Learning)


Analytics is the use of:
Data, information technology, statistical analysis, quantitative methods, and mathematical computer-based models to help data scientists to gain improved insight about their business operations and make better, fact-based decisions

  • Descriptive analytics
    • uses data to understand past and present
  • Predictive analytics
    • analyzes past performance
  • Prescriptive analytics
    • uses optimization techniques
