... square root of the appropriate diagonal ele- ment of ^ VV N =N. The asymptotic standard errors can be loosely thought of as estimating the standard deviations of the elements of ^ yy N , and they ... Limiting Behavior of Estimators and Test Statistics In this section, we apply the previous concepts to sequences of estimators. Because estimators depend on the random outcomes...
