Making Sense of Multivariate data using XLSTAT, UK 26-27 June 2018

The course will be held at the Premier Inn in central Reading, UK.

Reading has excellent transport links with rail links to all of the UK and a rail-air coach service to Heathrow Airport which runs every 20 minutes.

You can book overnight accommodation at the Premier Inn or a range of hotels within walking distance of the venue.

Making Sense of Multivariate Data

This course covers the excellent features in XLSTAT for investigating, visualising and modelling data sets with measurements on many variables. Depending on the application your focus may be on the objects measured (customers, products, physical samples etc. ) or the inter relationships between the variables themselves. There are multivariate techniques available to suit both these aims. Mathematical details are kept to a minimum and we focus on the interpretation of the outputs from XLSTAT and illustrate applications with case studies using data from consumer tests, instrumental analysis, manufacturing processes and biological data. We aim to explain the objectives of the techniques and to send you away with a better understanding of which technique to use when. There is plenty of opportunity for practice using XLSTAT through “hands on exercises” for which annotated solutions are provided and delegates are welcome to bring their own datasets to try the techniques.
