Statistical Computing Support

The Duke Empirical Research Support program provides basic assistance with statistical computing. We offer support for two quantitative research programs: Excel and STATA, and can recommend support sources for alternative programs. Assistance with using the qualitative program NVivo is also available.

Excel:

If you are interested in doing basic statistical computing, such as:

  • Descriptive statistics, including mean, median, mode, variances, ranges, and basic analyses of data.
  • Graphs, charts, and tables
  • Database management, including data from surveys and experiments.

We can provide support for these activities within Excel, and can perform many of the tasks for faculty interested in including basic empirical elements in their research.

STATA:

If you are interested in doing more advanced statistical computing, such as:

  • Modeling, including simple modeling, bivariate or multivariate regression, logistic regression, or more complicated methods
  • Time series or panel data analysis
  • Analysis of problem prone data, including data from surveys, survival analysis in experiments, or datasets with missing data
  • Database management, when the data is extensive or needs extensive transformation

We provide support and direction for these activities and can perform many of the analyses for faculty interested in more advanced empirical research.

STATA 12 is currently being distributed through the Duke's OIT office. The rates for purchasing are available online on STATA's website.

Online resources for working with STATA are also available. For a comprehensive guide, visit:

  • STATA Resources and Support
    Contains a comprehensive list of frequently asked questions, technical support, news and links to publications, forums and additional support. Published by STATA Press;
  • STATA Online Seminars and Classes
    Includes comprehensive tutorials for Stata (version 11 and earlier). It also includes manuals on additional software packages. Published by UCLA Consulting Services.

NVivo

NVivo 9 is a qualitative research software package that comes with its own programming language for analyzing codes, categories, and text and provides tools for the graphic representation of the relationship between them. It provides multidimensional matrix analysis of data categories for theory building. (View online tutorials)

Alternative Programs

Alternative quantitative statistical computing programs, including SPSS, SAS and R are available from Duke's OIT office, and local instruction is available. Although Duke Law School does not provide support for these programs, faculty can find local assistance through the Consulting and Data Services at Duke’s Social Science Research Institute and the Odum Institute at the University of North Carolina. Short courses are usually free, and all statistical computing programs are covered. In addition, there are extensive instruction web resources available for these programs.
