why would individuals cluster together at higher level why do individuals cluster together at certain firms? which is true with a firm-focused analysis? what is multilevel are predictors independent from firm why is the firm level important in multilayer modeling what is the difference between firm and firm which is a logical way to collect the dependent variables for individuals? what is meant by the term multilevel what is a multilevel model of a data structure? what would be logical to say for a dependent variable on the firm level? why do firms depend upon individual predictors why would firms have to be independent of each other what does firms focus on why is firm based predictors useful why do firms aggregate predictors are firms independent why would individuals cluster with respect to firms if the independent variable was aggregated why do firms have independent predictors that can be aggregated when comparing multiple levels of a firm, it would seem logical that individual predictors might be correlated with respect to firms.
