What is Gap Statistic for Cluster Estimation about?

The document presents the Gap statistic method for estimating the number of clusters in a dataset. The Gap statistic compares the within-cluster dispersion for different values of k to their expected values under a reference null distribution, such as a uniform distribution. It chooses the number of clusters with the largest gap as that number is most unlikely to have arisen by chance. The method was shown to outperform other existing indices in simulations with varying cluster configurations and amounts of
