Hi.
My question is very simple, if you know you can help us.
How can I, given a list of fundamentals, normalize that group as a whole?
By normalize is understood:
(x - x.mean()) / x.stddev()
Notes:
- I don't want to normalize each one, just the whole list of fundamentals
- The out of that magic Factor/Function must be the same length of fundamentals but, once again, normalized as a whole
