Dear SPM community,
My initial set of analysis using SPM99 as involved performing group
comparisons on 20 controls, 48 Alzheimers and 23 Lewy Body subjects using
the two sample t-test {one scan/subject}-design. Having
carried this out, I would like to extend the analysis and include covariates
in my design. The covariates I would like to include are Age (at scan time),
MMSE scores and severity of disease at the
time of scan.
Can anybody suggest the best way to do this in SPM99?
I shall look forward to hearing your very useful and appreciated comments!
Cheers
