Abstract
We propose a new algorithm for envelope estimation, along with a new root-n-consistent method for computing starting values. The new algorithm, which does not require optimization over a Grassmannian, is shown by simulation to be much faster and typically more accurate than the best existing algorithm proposed by Cook and Zhang (2015).
