In this book, the authors reject the theorem-proof approach as much as possible, and emphasize the practical application of econometrics. They show with examples how to calculate and interpret the numerical results. This book begins with students estimating simple univariate models, in a step by...

In this article, we describe the gwke82 command, which implements a measure of instantaneous feedback for two time series following Geweke (1982, Journal of the American Statistical Association 77: 304–313). Copyright 2013 by StataCorp LP.
