Modified double principal coordinate analysis (DPCoA) for composition of some fishes in Lake Mihaba

A method was developed to apply double principal coordinate analysis to compositional data with zeros. This method was then applied to the fish gut content data of some important fishes in Lake Mihaba, Agusan Marsh. The developed method involved applying rounded zero replacement to the original comp...
