Abstract

A new way of parametric bootstrapping allows similar construction of confidence ellipses applicable on all results from Multiple Factor Analysis obtained from the FactoMineR package in the statistical program R. With this procedure, a similar approach will be applied to Multiple Factor Analysis results regardless of the origin of data and the nature of the original variables. The approach is suitable for getting an overview of product confidence intervals and also applicable for data obtained from ‘one repetition’ evaluations. Furthermore, it is a convenient way to get an overview of variations in different studies performed on the same set of products. In addition, the graphical display of confidence ellipses eases interpretation and communication of results.
