And then very helpfully Joseph Coveney <>
posts the data in a nice do file (  (Not repeated

I ran the do-file Joseph provided and it appears to agree with
what Viviand says the book is reporting.  My guess is that
Viviand had some kind of data input or reshaping error when he
tried the analysis.

If you feel that something is still wrong, please email me and I
will try to help.
