i'm looking for some handy program/script to which i can pump data via stdin and which can present me some basic statistics of input data. for instance - provided with set of values separated by new line character i would like to get:
- average for all values
- average for data except 5% smallest and 5% largest values
- standard deviation
yes - i know, can be done with bash or awk, but maybe you already know something handy?
i'm perfectly aware of 'big cannons' like octave, r and some other - but i need something much simpler.
