 ArraysOfArrays provides two different types of nested arrays: `ArrayOfSimilarArrays` and `VectorOfArrays`.
 
 
 ## ArrayOfSimilarArrays
 
-An `ArrayOfSimilarArrays` offers duality of viewing the same data as both a flat multi-dimensional array and as an array of equally-sized arrays.

 `AbstractVectorOfSimilarArrays` supports the functions `sum`, `mean` and `var`, `AbstractVectorOfSimilarVectors` additionally support `cov` and `cor`.
 
-Methods for these function are defined both without and with weights (via `StatsBase.AbstractWeights`). Because of this, `ArraysOfArrays` currently requires `StatsBase`. It's possible that this requirement can be dropped in the future, though (see JuliaLang/julia#29974).
