    The construction of an asymmetric biplot for multivariate data sets
    (University of Namibia, 2015) Oyedele, Opeoluwa; Gardner-Lubbe, Sugnet
    A scatterplot is a useful statistical tool for representing samples as points and variables by means of coordinate axes. A form of scatterplot that can be used for multivariate data is the biplot. In this paper, the fundamental idea behind the biplot is discussed, before its construction. An illustration using an 11-dimensional multivariate data set concerning the relationships between chemical measurements and sensory descriptors is presented.

    The covariance biplot to reveal relationships between different sets of variables
    (University of Namibia, 2014) Oyedele, Opeoluwa; Gardner-Lubbe, Sugnet
    The biplot has many advantages, including demonstrating the association between samples and (or) variables of a data set graphically. In this paper, the covariance biplot is used as a visual tool for exploring the relationships between different sets of variables.
