Hello Nick,

thanks for your quick answer! Is there any already build-in way to extract those values or will i have to manipulate your command to do so?

On #1, you will find some technique in the code for -extremes- (SSC).

1. The command summarize is computing the 4 largest and smallest values.
Unfortunately the command is not storing them for the reason that it is a
build in command i cannot manipulate it to do so. To get this values from a
dataset is not that hard. i would just sort the values and take the values
of the observations _N, _N-1 and so on. But if i would like to use the
bysort "command" i would have to get the values of "subsamples" of my
datatset. This is not to hard if i use the preserve and restore commands.
But these commands unfortunately are VERY time-consuming. I have really big
datasets on hand and would like to obtain those values without the preserve
and restore commands. Any idea?
