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. Let's create a new variable for the natural logarithm of wage. . generate lnwage = ln(wage) We can fit a regression model for our transformed variable including grade, tenure, and the square of tenure. Note that I have used Stata's factor-variable notation to include tenure and the square of tenure.
