I am interested in knowing how friendship level is affected by both the respondent's characteristics and the relational variables regarding how the respondent communicates with a friend.
A friend of mine suggested that I could stack the data by making the friends of a respondent's individual cases, while duplicating the respondent's characteristic variables.
My question is, would I be able to apply regression (OLS, logistic, etc.) to this stacked data? The data stacking example I found online mostly do not involve the respondent's characteristics. Would mixing up variables at two levels violate any assumption? If so, what would be a good statistical method to analyze the data to achieve what I intended?
Note that this is for an academic paper (social science), so it has to pass reviewer #2's scrutiny. It cannot be "good enough for practice".
