You have at your disposal a lot of complicated data. For sure you want to find there important informations to understand the phenomenon the data describe. You count that this informations will lead to improving important processes within your company.

During the training you will learn how prepare data to analysis and next use appropriate methods to extract informations useful for your business. We will use R for this purpose.

Statistical system R ia a powerful and free tool. It is applied virtually in all fields of business and science. If you haven’t heard about R then learn why it is profitably to know R.

What will you learn?

  • Understand methodology of data analysis with use fo data mining methods.
  • Get useful practical skills.
  • Learn how to prepare your data for further analysis.
  • Data exploration and predictive models building methods: classification methods (used for development of predictive models), cluster analysis methods (discovering segments of similar clients), dimensionality reduction methods (graphical presentation of multidimensional data) and methods of discovering association rules (market basket analysis).
  • Get to know how assess predictive power of built predictive models.
  • You will work on these topics hands-on with a computer. It will take a half of the training.
  • You will get comprehensive materials and R scripts allowing you working single-handedly on your data.

For whom is this training?

Employees of departments working on data analysis and modelling (e.g. CRM, credit risk), controlling, audit, marketing, IT, and other departments who:

  • need to analyse data,
  • want to discover useful knowledge from data,
  • build predictive models.
