Dear all:
The table below is from the output of Winnonlin in word file, could
any one teach me how the column labeled Condition has been calculated,
I realized it is different from the condition number shown in PK Text
file, which is the square root of the ratio of largest to smallest
eigenvalues from X'X. I am not very sure if the log of ratio of
largest to smallest eigenvalues is the method they use, it seems not
(difference is around 0.04). I appreciate your consideration and help.
