Re: [Gretl-users] series transformation
If you had searched the command reference (pdf version) for your keyword
"summation", this would have led you to the 'cum()' function.
('cum'
stands for cumulation)
(Although I have to admit that searching for "sum" instead wouldn't have
helped you much. @devels: It probably would be nice to include an
overview of functions by topic in that document, similarly to the
overview for commands by topic. Also, in the embedded function
reference, cum() is listed under statistical, whereas diff() is under
transformations. I would suggest to move cum() to transformations as well.)
