Dear all,

Consider the scenario where there are *N* subjects each with at least *n* data points.

I am trying to figure out the difference between fitting a *multilevel regression* model assuming **No Pool** to all subjects and fitting the regression model separately to each subject.

- Do the two modelling approaches imply that each subject is independent (that is has its own parameters)?

I have asked for a clarification of the two approaches as I am told to fit a model separately to each subject data, but then I am wondering if wouldn’t this be same as fitting a multilevel **No Pool model.**

Thanks for the help
