... cross section analysis the asymptotics is as the number of observations, denoted N throughout this book, tends to infinity. Usually what is meant by this statement is obvious. For panel data analysis, ... the time series dimension and let the cross section dimension grow. The research on asymptotic analysis with these kinds of panel data sets is still in its early...

Unfortunately, complications often arise in the collection and analysis of economic data because of the nonexperimental nature of economics. ... function of x.Wheny and x are random, it makes sense to use the right-hand side of equation (2.8), but where f ðxÞ is the conditional mean, mðxÞ.

... 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...
