Building Better Econometric Models Using Cross Section and Panel Data, livre ebook

Many empirical researchers yearn for an econometric
model that better explains their data. Yet these researchers
rarely pursue this objective for fear of the
statistical complexities involved in specifying that
model. This book is intended to alleviate those anxieties
by providing a practical methodology that anyone
familiar with regression analysis can employ—a
methodology that will yield a model that is both more
informative and is a better representation of the data.
This book outlines simple, practical procedures
that can be used to specify a model that better explains
the data. Such procedures employ the use of
purely statistical techniques performed upon a publicly
available data set, which allows readers to follow
along at every stage of the procedure. Using the
econometric software Stata (though most other statistical
software packages can be used as well), this
book demonstrates how to test for model misspecification
and how to respecify these models in a practical
way that not only enhances the inference drawn
from the results, but adds a level of robustness that
can increase the researcher’s confidence in the output
generated. By following this procedure, researchers
will be led to a better, more finely tuned empirical
model that yields better results.
