You can standardize them yourself. rvar.mgh is the residual variance and Xg is the design matrix. Between those and the beta values, you can standarize the betas

Hi Dr. Greve,

Thank you for your response! Not sure if you already addressed this, but my second question was whether there is a way to derive the (95%) confidence intervals for my covariates that were included in the mri_glmfit analyses?

Thanks again!

Hi,

I had a couple additional questions related to this topic.

1. The beta-coefficients I derived from using the mri_segstats command with the input beta.mgh, are these values unstandardized?
Yes, that have not been standarized

2. Just wondering, is there a possible way to also derive 95% confidence intervals for my covariates that were included in the mri_glmfit analyses?

Thanks so much for your help!
