WebK-means clustering serves as a useful example of applying tidy data principles to statistical analysis, and especially the distinction between the three tidying functions: tidy () augment () glance () Let’s start by generating some random two-dimensional data with three clusters. Data in each cluster will come from a multivariate gaussian ... WebDunn's index is the ratio between the minimum inter-cluster distances to the maximum intra-cluster diameter. The diameter of a cluster is the distance between its two furthermost points. In order to have well separated and compact clusters you should aim for a higher Dunn's index.
