major comments: NA
minor comments:
1. a short description of the LCA would be useful for the less familiarized readers
2. the selection of 5 classes seems rather empirical and should be better
supported by scientific arguments
3. authors should comment briefly on the practical usefulness of this analysis
Level of interest: An article of importance in its field
Quality of written English: Acceptable
Statistical review: Yes, but I do not feel adequately qualified to assess the
