Erratum: Speaking Stata: Loops, again and again

Abstract: The spaghetti problem arises in graphics when multiple time series or other functional traces show mostly a tangled mess. The related paella problem (often experienced but not usually named as such) arises for multiple patterns combined in scatterplots. This column is a sequel to those in Stata Journal 10: 670–681 (2010) and 19: 989–1008 (2019). The focus is on what are here called front-and-back plots, in which each subset of data is shown separately with the other subsets as backdrop. The strategy is thus a hybrid of two more common strategies, showing each subset separately (juxtaposing) and showing subsets to- gether (superimposing). A new command, fabplot, is introduced and used in examples.

Keywords: fabplot; graphics; front-and-back plots; juxtaposing; superimposing; line plots; scatterplots; panel data; longitudinal data; quantile plots (search for similar items in EconPapers)
