Witryna2 lut 2024 · Labeling logarithmic axes in Stata graphs I could also also produce nicer labels by using "10 {sup:`x'}". However, I cannot find the solution to the following additional elements: the range of the axis labels would run from 10^-10 up to 10^10. Moreover, my baseline is ln, so log values are 2.3, 4.6, etc. Witryna24 sie 2014 · For completeness, Stata will produce a missing (.) if it is instructed to take the log of a non-positive number. – Roberto Ferrer. Aug 24, 2014 at 13:30. 1 @Metrics log(x + 1) is not something to do routinely without waving a big flag that you are doing it. It's a common trick in some areas, but regarded as an unjustifiable fudge in many others.
