did you see the text where it says "If you seek help with this problem,
make sure to send:" and then it gives a list of things to send? There
will be a file called y.fsgd in the output, make sure to send that

External Email - Use Caution
Hi experts,
I have examined the relation between LGI and a behavioural continuous
scale (SCQ) on QDEC while controlling for sex, age and surface area in
my model. When I want to do another analysis, doing exactly this but
also controlling for diagnosis as well, QDEC gives the following error:
ERROR: matrix is ill-conditioned or badly scaled, condno = 1e+08
--------------------------------
Possible problem with experimental design:
Check for duplicate entries and/or lack of range of
continuous variables within a class.
If you seek help with this problem, make sure to send:

2. The FSGD file (if using one)
3. And the design matrix above
Attempting to diagnose further
SumSq: Min=0.488835 (col 11), Max=3.834060 (col 6)
... could not determine the cause of the problem
My understanding is that QDEC allows for controlling for 2 discrete
variables, thus I don't know what I am doing wrong if I also control
for diagnosis (in addition to sex)?
I would really appreciate your help,
Thanks so much,
Avi
