11. This process can be repeated to remove more error terms to get even better approximations. 12. Assumptions about the error term determine whether we speak of fixed effects or random effects. 13. In this specification the error terms are white noise, so statistical inference is valid. 14. If a dependent variable is error term . 15. Again, the zero in the transformed circle equation is replaced by the error term . 16. The error term is still restricted to be of an AR ( 1 ) type. 17. Discarding the " error term " is accomplished by an application of the standard part function. 18. For example, serial correlation ( error terms correlated across time ) has multiple distinct meanings. 19. Error terms can be correlated across time for the same series, individual, and horizon.20. Similarly, a small error term collapses a transcritical bifurcation to two saddle-node bifurcations.
