Making Significance (Sense) Ulf H. Olsson
Making Sense If the model is correctly specified, different estimators should have similar values asymptotically (White, 1994) <=> If the different estimators do not have similar values asymptotically, the model is misspecified 1) Use at least two estimators; if they differ the model is misspecified; 2) Across-method variability can be used to assess what parts of the model, if any, are close to the true model? ? Ulf H. Olsson
Making Sense A strong theory will give precise predictions! Ulf H. Olsson
Making sense is more important than making numbers, it is even more important than making significance ? Ulf H. Olsson
