1.1 Welcome

This book was originally (and currently) designed for use with 2122-EN0P15-ECONOMETRICS-II, at the Antonio de Nebrija University (Madrid). It may certainly be used elsewhere, but any references to these notes should use the original references cited at the end of each section or included as footnotes.

These notes are under active development

Since this book is under active development you may encounter errors ranging from typos to poorly explained topics.

These notes are possible due to the existence of the incredible pieces of software by Xie (2016), Xie (2020), Allaire et al. (2020), Xie and Allaire (2020), and R Core Team (2020).
