I must say it's strange to see a D'Errico contribution receive 2 stars.
So I'll repost my original rating (lost when John temporarily removed this contribution last year).
An interesting and potentially very useful tool. I'm reviewing both this implementation as well as Pearson's book and webpage.
The code appears well-commented and carefully written but I'll hold off on a rating until I have tested it more using my own data.
There is just so much to learn from this topnotch collection of powerful routines.
