A great book to get you started in the econometrics. In the first chapters briefly basics in statistics and stochastics be repeated before it starts with Econometrics from the third chapter. Step by step you will be introduced to regressions etc, this is all explained in simple examples. From me a buy recommendation for those interested without the knowledge or undergraduate students. A little disturbing, I find that many derivations are explained only the back of the Annex. This is cumbersome but also not relevant for a basic book, therefore, still 5 stars
