Rejoinder to the discussion of 'Model-based clustering and classification with non-normal mixture distributions'

摘要

We thank the discussants for their thoughtful comments on our paper and the raising of issues for further examination. As it is not possible to respond to all comments here, our intent is to cover at least the main scientific points made. In responding in the sequel to the four contributions of the discussants (in alphabetical order), we shall refer to Christian Hennig as CH, Luis Angel Garcia-Escudero, Alfonso Gordaliza, and Augustin Mayo-Iscar as EGM, Giuliano Galimberti and Angela Montanari as GM, and Paul McNicholas, Ryan Browne, and Paula Murray as MBM. Our response to the latter contribution is somewhat longer than to each of the others since a number of questions are asked of us. We are keen to answer them as it gives us the opportunity to clarify further the underlying assumptions and hence the consequent limitations of the various proposals.
