Hello SR Millis,

the highest condition index is 57.29. regarding the variance
decomposition proportions, there are 6 above 0.5 when the condition
index is ~30. . seems a bit weird that the table using coldiag2 gives
me 17 indexes even so i only have 16 variables.

thanks again,

george



thanks again

george
