Hi list, I have some questions, please. I performed linear regression by qdec to find the regions where the cortical thinning correlates with neuropsychological test (NPS), taking in account 3 nuisance factors. A- I individuated some posterior regions and now I'd like to build a table with partials correlations of individuals ROIs with NPS. How can I obtain the values for each region? B- I'd like to obtain the covariance matrix of the regression made between cortical thickness, group and covariates. How can I do it? C- Is there a specific reference for qdec? Thank you very much,
Stefano
