Brief History

We launched www.OpenDoors.Pk back in 2009 for sharing class notes, slides, and quizzes with our students. With the passage of time, we gradually added more contents to the site. These included annual reports of the companies listed at the Pakistan Stock Exchange, monetary statistics, macroeconomic data, and much more. These contents attracted significant attention from all over Pakistan.

We received a large number of requests for additional data as well as for guidance on research methods. Responding to all such requests was simply not possible due to time and other constraints.  Further, collecting additional data and updating existing data sets seemed impossible without getting paid help from others. Therefore, we decided to add a paid section to our website. The paid section of the website proved to be a life blood for the website.

Gradually, we added several paid services to the website. This website is an off-shoot of www.OpenDoors.Pk. We have the same motivation to serve the research community by offering a variety of services such as data management, guidance in statistical tools, and writing dedicated packages. Our group, StataProfessor, is led by Dr. Attaullah Shah. He has vast experience in research, student supervision, software development, and academic journals. His resume is given below:
