摘要：A biplot is a graphical representation of two-mode multivariate databased on markers for rows and columns often provided in a two-dimensionalspace. These markers define parameters that help to interpret goodness offit, quality of the representation and variability and relationships betweenvariables. However, such parameters are estimated as point values by thebiplot, thus no information on the accuracy of the corresponding estimatorsis obtained. We propose a graphical methodology, that may be considered asan inferential version of a biplot, based on bootstrap confidence intervals forthe mentioned parameters. We implement our methodology in an R packageand validate it with simulated and real-world data.
