Research Interests

  • Stata statistical software
    I have contributed user-written programs (, including (1) table1_mc ... create "table 1" of baseline characteristics for a manuscript, (2) precombine... examine n ≥ 2 datasets before combining, (3) labeldatasyntax... produce syntax to label variables and values, given a data dictionary. Some of these commands are useful for the systems for the transparent and reproducible organisation of statistical analyses of a study’s data, while others concern determining the sample size of a RCT at the trial design stage. I also teach Stata courses.
