Learn about subscripting under -by:-. Then translate your favourite formula to subscript language.
There is a tutorial on -by:- in

Q1/02 SJ 2(1):86--102 (no commands)
explains the use of the by varlist : construct to tackle
a variety of problems with group structure, ranging from
simple calculations for each of several groups to more
advanced manipulations that use the built-in _n and _N
If log GINI is 3.68, say, then GINI is perhaps exp(3.68) ~ 40 (are you measuring in percents) or 10^(3.68) ~ 4786 (seems unlikely). There is probably a substantive debate on what metric which is best to compare GINI on, but I'm unequal to the challenge.

I have a 5 yearly panel data set covering 107 countries. I have to calculate the growth rate of different variables.
I have tried the various formulas given in the archive of STATALIST but could not find the solution. My data looks like:
Countries Years log of GINI
A 1965 .
A 1970 3.68
A 1975 2.34
A 1980 .
B 1965 .
B 1970 3.24
...
I want to calculate the growth rate of log of GINI for 1965, 1970 etc for each country. The years are 1965, 1970 ..... to 2010.
