Dear Statistics Help users,

This is my first post, and I am really hoping someone will be able to answer my question.

I am looking for 2 definitions:
1) "sample-to-sample variability".
2) "whithin-sample correlation"

I have some data analyzed for me with (PA-GEE) GLM regression, and the results say :
" sample-to-sample variability is 0.25, and within-sample correlation is 0.647"

How do I interpret this?

Thank you very much!
