When you are conducting research, you often only collect data of a small sample of the whole population. WebbIt’s not that it underestimates the parameter values themselves, but the standard errors of actual model effects. So yes, if you’re just estimating means and correlations, you’re fine. But if you want to impute data points and use those in a model, your software doesn’t know that those are estimates and not real data points.
