Hello, 

I am inquiring about the assumptions of normality and heteroscedasticity of residuals, specifically - when running a multivariate regression using the CONN toolbox, are these assumptions already controlled for in the second-level results?

I have used the toolbox to look at the linear association between 4 clinical variables and FC within a group of subjects. I am wondering if the significant results that I am seeing have normally distributed residuals and if the residuals have equal variances - is there a way for me to extract residuals to examine/plot them or has this already been taking into account?

Likewise - are there any papers that I can reference that explain how CONN toolbox deals with these assumptions?

Many thanks, 

Jenna
