High bootstrap value meaning

WebOverview. pvclust is an R package for assessing the uncertainty in hierarchical cluster analysis. For each cluster in hierarchical clustering, quantities called p-values are calculated via multiscale bootstrap resampling. P-value of a cluster is a value between 0 and 1, which indicates how strong the cluster is supported by data. Web14 de dez. de 2024 · The high bootstrap value tells us that the sampling variance for this branch is low.
