Yes I have, but what I gathered from the reports was that it basically just
said negative t values can occur when the hypothesis is based on the minimum
t statistic...it didn't really explain the validity or what the negative t
values really meant. Although maybe I didn't get much out of the articles
since statistics is not my forte....I'm still learning!
Any further explanation would be much appreciated, especially on displaying
negative t values!
Thanks
