## Abstract (arXiv)

A faster implementation of mixtures of Manly transformations is proposed. This method, called FastManly, uses Newton's method for optimization in an EM gradient algorithm instead of Nelder-Mead in a traditional EM. A gradient and full Hessian are derived. Simulations show improved performance with noticeable speedups.
