extending models with statistic capabilities
Hi,
I have several models in my app which contain several numerical attribute.
Ex.: stock model; attributes: bid, ask, value,..
todays_values_of_Google = [ [#Stock: id=1, bid = 1.5, ask = 1.5, value =
1.5, time=..., ...], [#Stock: id=2, bid = 1.45, ask = 1.5, value =
1.45,..],... ]
Now I would like to have some statistics. I saw the possibility of open the
array class and add some functions like:
Class Array
def mean; blabla ; end;
...
end...
