Package: SaturnCoefficient Title: Statistical Evaluation of UMAP Dimensionality Reductions Version: 1.6 Authors@R: person("Davide", "Chicco", , "davidechicco@davidechicco.it", role = c("aut", "cre"), comment = c(ORCID = "0000-0001-9655-7142")) Description: A metric expressing the quality of a UMAP layout. This is a package that contains the Saturn_coefficient() function that reads an input matrix, its dimensionality reduction produced by UMAP, and evaluates the quality of this dimensionality reduction by producing a real value in the [0; 1] interval. We call this real value Saturn coefficient. A higher value means better dimensionality reduction; a lower value means worse dimensionality reduction. Reference: Davide Chicco et al.
