Hi,
I'm getting some unexpected results using the spm_t2z function....
say we get some t-score between 0 and 5 and convert them to z scores
with 8 degrees of freedom;
t = rand(1000,1)*5;
z = spm_t2z(t,8);
plot(t,z,'.')
I get a gap in the plot in values around t=0,65, and the z scores are
all negative!
The distribution looks like the negative of what it should look
like...
could someone shed some light on this?
thanks
-Luis
