Dear SPM users and developers,
I have a regression between hallucination level and activation level in
a set of subjects.
I have looked for significant regions. Then I would like to plot the
variables to see how the regression works.
I ask for a plot of fitted responses, with adjusted data. Then I plot
against an explanatory variable, hallucinations (that has been coded in
a column).
Then I get a nice plot, with fitted and 'plus error' data. In those data
AFAIK, Y corresponds to fitted data and y corresponds to 'adjusted'
data. The problem is, when I see the Y data, the regression is apparent.
If I look at the y data, there is no regression at all.
What importance has the 'y'? Could I use the 'Y' as real fitted data?
Thanks in advance,
Juanjo
