SDBP: An easy-to-use R program package for assessing reliability of estimated phylogenetic trees based on the speedy double bootstrap method

Evaluating the reliability of estimated phylogenetic trees is of critical importance in the field of molecular phylogenetics, and for other endeavors that depend on accurate phylogenetic reconstruction. The bootstrap method is a well-known computational approach to assessing phylogenetic trees, and more generally for assessing the reliability of statistical models. However, it is known to be biased under certain circumstances, calling into question the accuracy of the method. Therefore, several advanced bootstrap methods have been developed to achieve higher accuracy, one of which is the speedy double bootstrap approach (sDBPmethod). In the phylogenetic tree selection problem, it has been shown that the sDBP-method has comparable accuracy to the double bootstrap approach and is much more computationally efficient. In this study, we thus develop an R package named SDBP, which is an implementation of our sDBP-method on a statistical software R to assesse the reliability of phylogenetic trees. We are confident that biologists will benefit from our sDBP-method and SDBP
