WebOct 6, 2024 · So Stata sees square brackets before a comma, so it thinks that it has to be a weight. The first word within the brackets specify the type of weight, so Stata sees if and thinks that you want to specify a weight of type if. However, it does not know a weight type called if (and neither do I). It only knows pweight, aweight, fweight, and iweight. http://fmwww.bc.edu/repec/bocode/c/cdfplot.html how many episodes are in my name
