Hi,<br><br>I&#39;m still trying to figure out how to run a regression analysis using functional data.  I found the information in using qdec,  however, the example uses a between subject design (with age/gender) and looks at thickness measures.<br>


<br>I tried creating a qdec.table.dat, but I am unsure how to do it with a within subject design, as when I ended up with it reading the file as me having 16 subjects instead of 8.<br><br>What I have is a discrete variable of load (high and low) and a continuous variable of set size (1,3,6), but I want to correlate the data with the performance at each set size for each load as well as load.<br>


<br>This is what my qdec table looked like:<br><br>fsid      dist     k1    k3     k6<br>subj1   low     1      2.9    4.0<br>subj1   high   0.8    1.3    2.0<br>subj2   low     0.9   2.9   5.7<br>subj2   high   0.9   1.9    1.4<br>


...<br>subj8   low     0.8   2.4    2.5<br>subj8   high    0.8  1.4     2.7<br><br><br>Can anyone tell me how to appropriately structure this to do what I want?<br><br>Thank you!<br><br>Katie<br>
