jointly in a biplot where the projection of a row point onto a column point vector followed by a multiplication by the length … propose a new visualization: after a 90 degrees rotation of the row points, the areas spanned by a triangle of a row point, a … column point and the origin estimate the data values. In contrast to the projection biplot, the areas spanned by different …

In order to interpret the biplot it is necessary to know which points – usually variables – are the ones that are … important contributors to the solution, and this information is available separately as part of the biplot’s numerical results …. We propose a new scaling of the display, called the contribution biplot, which incorporates this diagnostic directly into …
