Unweighted and weighted unifrac distances
WebA third UniFrac metric, generalized UniFrac [6], was developed to strike a balance between the biases of weighted and unweighted UniFrac. Aitchison Distance One of the concerns when dealing with microbiome data is that many people treat read counts as absolute abundances of microbes, and apply statistical tests that are designed for absolute … WebOct 24, 2024 · Generalized UniFrac distance contains an extra parameter α controlling the weight on abundant lineages so the distance is not dominated by highly abundant lineages. α=0.5 is overall very robust. The unweighted and weighted UniFrac, and variance-adjusted weighted UniFrac distances are also implemented. Usage
