Accessing the H drive
- VPN to the University using GlobalProtect, see here https://workcontinuity.princeton.edu/remoteaccess. The portal address is vpn.princeton.edu. This will also allow you to access DSS data sources restricted to Princeton students, faculty, and staff.
- If you have a Mac, see instructions here http://helpdesk.princeton.edu/kb/display.plx?ID=9268
- If you have Windows, see instructions here https://dss.princeton.edu/training/HDriveWindows.pdf
Once you connect, you may have an icon with your username and the word ‘alias’, that is a shortcut to your H drive, click on it and the H drive folder will open. If you are running out of space in your H drive, send a request for more to OIT by email at email@example.com.
If you do not see the alias icon, then the H drive is in your ‘finder’ or Windows Explorer as a drive that starts with something like ‘files//:….” or "files.princeton..."

Overview of consulting services
Statistical consulting services are available to currently enrolled/employed members of Princeton University. DSS consultants provide statistical and software assistance in quantitative analysis of electronic data as
part of independent research projects, such
as junior papers, senior theses, term papers, dissertations, and scholarly articles. We advise about the choice and application of quantitative methods, the conversion of data from one format
to another, and the interpretation of statistical analyses. The statistical packages supported are Stata, SPSS, and R.
The lab is very crowded from February to April with primarily juniors and seniors working on their junior paper or senior thesis. Please plan ahead if
you need extensive assistance.
NOTE: We do not provide assistance with homework assignments, problem sets or take-home
exams but students are welcome to use our online resources, tutorials and computing resources.
The DSS computer lab is located at A-12-G (A-floor, click here for a map) in Firestone
The lab is open when Firestone Library is open. If you would
like to use lab computers and do not need assistance, you may come in anytime when the library is open. Assistance is
provided according to the staffing schedule posted on the sidemenu on the left. If you need assistance but can not come
during the staffed hours, please email email@example.com . When requesting an
appointment, and to make the most out of it, please provide as much information as possible so we can better plan a way
to help you.
Making the most from the consultation
Before coming to the lab:
At an earlier stage in your research:
- Have a feasible research question, click here for some tips on crafting research questions
- Try to locate the data you need, click here for some tips on finding data
- Identify the variables relevant your research question.
- Use the coodebook to understand your data
- Unlike homework assignments independent research can't be done overnight. JPs, senior theses, term papers, dissertation take time and resources. Once you define your research question you need to get the data, select the variables, clean and prepare them for analysis, select the model, interpret the results, write the conclusions. So, plan ahead and start as early as possible.
During or at a later stage in your research:
- Make sure your advisor is on board and approves what you want to do. Remember, he or she will grade your work!
- DSS consultants can guide you throughout your research but you are responsible for what goes into your paper.
- Have a plan for your project as a whole. A written time-line and "to-do" list will be veryhelpful. During busy times, consultants may not be able to give as much personalized attention, so knowing specifically what you need to ask will make your time more efficient.
- Keep a log of everything you do related to your research, even steps that did not work. This will come in handy by the time you write the final version of your paper and, most importantly, the methodology section.
