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:

November 29, 2018at 7:16 pmDear Attaullah Shah, good afternoon.
I’m a Stata user, but some programming things I do not understand yet.
I’ve been looking at forums like https://stackoverflow.com/questions/53524560/looping-and-storing-beta-coefficients-after-regress-over-files#new-answer
answer to a question I have.
I am not able to make my loop save the results after regressing over files (betas, t, R2 and N), with all my datasets. I have 11 named 2005.dta to 2017.dta (except for 2009) contained in a folder (F:\datasets).
The objective is to use asdoc, and to generate a summary table of the estimates I make. The code that I have written is the following.
cd "F: \ datasets" local i: dir. files "* .dta" foreach file in `i '{ asdoc reg and x1 x2 x3, append nest rep (t | se) title (Table 1 MCO per year) dec (3) }But the result is that asdoc saves the results of a single database (only the first – 2005) 11 times and does nothing for the others.
If you could have time to help me solve this problem I would thank you very much.
Cheers Juan

November 29, 2018at 10:03 pmJuan Miranda: The question you have asked on stackoverflow is on hold, so I cannot add my answer there. The loop you are using does not use asdoc on each data set that you have. So the correct code would be:
cd "F:\datasets" local i : dir "F:\datasets" files "*.dta" foreach file in `i' { use `file', clear asdoc reg y x1 x2 x3, append nest rep(t) title(Table 1 MCO per year) dec(3) save(reg) }Please also note that there should be no space between
repand(t | se). The same applies to other options of asdoc.Also note: the option
rep(t)is used to report t-statistics. Instead, if you want to report standard errors, you would userep(se). However, you cannot use bothrep(t|se). Perhaps, you copied this from the help file of asdoc, where the symbol pipe is used to denote that one of these can be used.Juan Miranda
December 3, 2018at 11:52 pmThank you very much, and of course I am going to make references to your Asdoc program.
A greeting and good forecast
