Software & Code

Tools, Scripts, and Reproducible Workflows

I share here code and tools related to my research and teaching. I work primarily in R, Mplus, and Stata.

This section is under construction. Code will be published as research projects allow.

Legacy Programs (Delphi)

More years ago than I care to remember, I developed a few small programs in Delphi for teaching purposes. Here are the ones that survived successive computer upgrades. They are in Spanish, Windows-only, and come with no documentation, but they still work.

  • PhiLambda (philambda.exe): A small utility for estimating the PhiLambda coefficient (reliability of a dichotomous decision in Generalizability Theory), based on the ANOVA table from the RELIABILITIES menu in SPSS.
  • WinError (WinError.exe): An interactive tool for explaining what the standard error of measurement is and what it is used for.
  • Notas (notas.exe): A quick converter from percentage scores to Chilean grades (1 to 7 scale).
