Quantile-quantile plots in the precise sense of scatterplots showing corresponding quantiles of two variables have long been supported by official command qqplot. That command is generalized here in several ways in a new command, qqplotg. In this art... Read More about Speaking Stata: Quantile–quantile plots, generalized.

Speaking Stata: The joy of sets: Graphical alternatives to Euler and Venn diagrams (2024)
Journal Article
Cox, N. J., & Morris, T. P. (2024). Speaking Stata: The joy of sets: Graphical alternatives to Euler and Venn diagrams. The Stata Journal, 24(2), 329-361. https://doi.org/10.1177/1536867x241258010

Membership of overlapping or intersecting sets may be recorded in a bundle of (0, 1) indicator variables. Annotated Euler or Venn diagrams may be used to show graphically the frequencies of subsets so defined, but beyond just a few sets such diagrams...
