This webpage has been upgraded as a book “How to get started with Stata”, which has been published in Amazon

As the saying goes, everything is difficult at the beginning. An entry-level textbook is far more important than we might think. The best entry-level textbook guides you start a topic smoothly and gives you confidence to go further. On the contrary, you might get confused at the beginning if an entry-level textbook is unsatisfied.
