Re: st: How to graph

[Carlos Avellaneda Suárez <carlos.avellaneda8@gmail.com>]

Hi Kisil,
One solution is to collapse your dataset. Here is an example you can
reproduce in a do-file:
*****Begin Example*****
webuse nlswork
preserve
collapse (p10) p10=ln_wage (p20) p20=ln_wage ///
(p30) p30=ln_wage (p40) p40=ln_wage (p50) p50=ln_wage ///
(p60) p60=ln_wage (p70) p70=ln_wage (p80) p80=ln_wage ///
(p90) p90=ln_wage , by(year)
tsset year
tsline p*
restore
*****End*****
By the way, why would you estimate a percent change in a log variable?
Remember that the first difference of the logarithm of a variable
approximates to the percentage change of the unaltered variable. With
the previous example, you just have to generate new variables of the
first difference of each percentile.
Hope this helps.
Carlos
