Re: independent variables - ln

Hi there,
If x1,...,xn are random independent variables,
it is true that ln(x1),...,ln(xn) are also independent?


I substituted "independent random variables" for "random independent variables" in the above, in which case I believe my response is correct.

I thought that QUESTION wss so infantile that was not worth
even a one line comment, such as:

What is the meaning of your "independent" in
"random indepdent variables"?

I would argue that *all* serious questions, no matter how trivial, are worthy of a reply. The question posed seemed plain enough to me, and I think we risk driving the statistically curious away if we demand that posters to this group phrase (or re-phrase) queries in technically correct, completely unambiguous language. The very reason most part-timers stop here is because they're *uncomfortable* with statistics and statistical language!

That being said, perhaps I should have clarified my assumptions about the question being asked (i.e. independent = statistically independent) in my response.
