Hi, sorry for this e-mail, but I have not found any other way to find
this answer.
I am an economics student from Finland that are using Gretl, and
finding it useful tool to analyze data.
We were wondering if Gretl had a function for dividing groups into low
and high respondents, in other word we want to test a part of a
population (in OLS) who have marked the highest scores in a survey. We
want to test this against other answers in the same survey, but are in
doubt that Gretl understands that person 1 is the same person when we
change the order of respondents by sorting them in the dependent value
and then setting the range to half of the population .
Hi,
if u r sorting the dataset as a whole the unit identifiers r sorted as well.
If u have a unit and time dimension u'd better use the panel option for
defining the dataset structure.
If u r working with matrices in the first column the unit identifiers
need to present and r then sorted along with the variable of interest.
Cheers

I would really appreciate an answer, thank you.
Best regards
