Introduction

Develop the skills to help your organisation make better risk/reward decisions.

What is Predictive Analytics?

Mathematical tools that analyse current or historical facts to predict future unknown events. Using Support Vector Machines, usually through an Excel front end, organisations with large data sets, such as customer information systems can classify and predict likely behaviours and outcomes.

How can we use them?

Z/Yen Group developed one of the first tools for Predictive Analytics more than 10 years ago. We have been working in multiple sectors which include: 


Until very recently using Predictive Analytics needed proprietary software and serious data skills. That is changing fast – the software tools are often free, and can be used by data jockeys with just a little additional training.

How to get started

Based on this experience and success, Z/Yen have developed a set of training sessions to enhance understanding of predictive analytic methods for various organisations. There are two main types of courses:

  • An appreciation course for senior managers and information leaders that explains why they need to know about this, and exactly how much they need to know themselves – so they can ask the right questions and understand the answers.
  • A practical course for experienced data experts or “ninjas” with good Excel and analytical skills who want to be able to get more from data.

Recognising that every organisation is different, the course modules can be mixed and matched, to tailor exactly what your organisation needs to get out of them. With more than 100 modules available, the courses can deliver exactly what you need – the table on below provides examples showing the scope and breadth of modules available.
