Description

Compositional and ratio data are common in a wide variety of environmental applications. Ratio data present problems because the denominators and numerators are random variables, while compositional data are constrained by the condition that all the components sum to one. This session presents new research and applications that draw parallels between the two problems and seeks common solutions.
