PAPER CLIPS: Multi-omics Compositional Data Analysis (Part 1/2)
This video talks about the integrative analysis of two separate compositional data sets, for example metagenomic and metabolomic data collected in parallel on the same samples. It introduces the "2-simplex problem", and highlights the importance of performing log-ratio transformations on each of the data sets separately, rather than jointly.
