Hi again,
to correct my last email. That is not 'everything' you need to
know. I have looked and I cannot find any results on the statistical power
of generalized inverse based methods or the statistical robustness. As I
have come across similar problems with some data I am also very interested.
Best regards,
Ben Flood

Subject: generalised inverse matrices
Hello All,
I am having issues with singular matrices because the number of variables
(linear morphometric measures) I have far exceeds the number of samples. I
don't wish to introduce a bias into my analyses by selecting variables to
include/exclude from my data matrix, hence I am wondering about the validity
of using generalised inverse matrices.
Is the use of generalised inverse matrices a valid/ accepted one?
Are generalised inverse matrices statistically robust and will people
believe my results?
Has anyone published using generalised inverse matrices?
How would I defend the use of generalised inverse matrices?
Thanks in advance,
Brett Human
