Using the package AxisArrays.jl : how to keep the type AxisArray when making operations?

I would like to make descriptive statistics on an AxisArray{Float64,3,…}. For instance, my AxisArray has 3 axes (N, V and T) and I am looking for an operation allowing to divide each component at T=t by its value at T=t+1. However, I can not figure out how to do it efficiently without loosing the type AxisArray. I would like to have, at the end, a new AxisArray but with 2 axes : N and V. Does anybody have a solution to do that ?
Thank you very much in advance.
