Thank you. My university's classes are all going online and your videos are a great resource for my econometrics students.

Would a functional misspecification essentially be a form of omitted variable? As in say happiness = c + dogs + e vs. happiness = c + dogs - dogs^2 + e ??

Can you have any of these 3 situations (omitted variable, functional misspecification or measurement error) and still get unbiased estimators?

What do you mean that underestimating our independent variables/Omitting variables will be "carried over to other periods"?
@DimitriBianco6 жыл бұрын
If the errors are serial correlated then an over-estimation in one period will result in an overestimation in the next period. This can be caused by an auto-regressive effect from the independent variable (i.e. people slowly adjust to changes in their environment) OR it can be the signal/pattern of a variable that is missing (omitted variable).

@@DimitriBianco where did 'periods' come from ? Are you talking about time series ? Because I am thinking of general linear regression which is applied once only

Thank you for the lecture! One thing I dont get is what does "other estimator" mean? Estimator given by MLE or other method? Can you give an example?

GLS and fGLS can correct for serial correlation and are better than OLS given they can be BLUE. Some examples of these are the cochrane-orcutt and praise-winston estimations.
