Below, you can find my Econometrics Lecture Notes (in Turkish) that have been published as opencourseware by the Turkish Academy of Sciences (TUBA). The notes follow the subject list of Gujarati and Porter's Basic Econometrics text book.

Gretl in Turkish main window
Gretl estimation window
Gretl (Gnu Regression, Econometrics, and Time-series Library) is a comprehensive econometrics package, developed with the C programming language. It is free and open-source software. It can be freely redistributed or modified under the terms of the GPL3 licence published by the Free Software Foundation. Being free makes gretl an ideal tool for the classroom environment; while being open-source makes the program a transparent, reliable and universal choice for scientific studies.
Since its initial version in 2000, gretl has shown significant progress and today it has reached more than 700,000 lines of programming code. The latest versions of the software offer, in addition to an easy and intuitive graphic interface, a wide selection of tests and estimators, an integrated scripting language, high quality plots, and many other advanced features. According to the Open Hub website, which compiles statistics regarding open source software, gretl currently has 24 active developers and contains approximately 180 human years worth of effort based on its lines count. Accordingly, the cost of developing the software from scratch with a 60,000 dollars annual sallary per programmer would be calculated as nearly 10 million US dollars.
I started using gretl for the first time during my economics doctoral studies in the US and, in time, I became one of its developers. Aside from hundreds of improvements and error corrections, I have played role in the empirical testing and documentation of many computations in gretl. In addition, I have also published various gretl related articles and reviews in highly respected international scientific journals and conferences.
In 2008, I meticulously translated gretl's user interface and its website into Turkish. Thereby, gretl has become the first econometrics software that supports the Turkish language. I continue to update and improve the Turkish translation of gretl to this day. I hope that my efforts will be helful for many Turkish scientists in their research, and also contribute to the development of Turkish as a language of science.
