how do you take the natural logs??
I think this is why I can't do my problems, maybe I'm missing some basic concepts.
ok, so let [tex] L({\theta}) = \theta^{-2n} \prod y e^{-(1/theta)}\sum y [/tex]
taking the natural log, I get
[tex]ln L(\theta) = -2nln\theta + ln \prod y - 1/\theta \sum yi [/tex].
I don't know, how did they do that?
and later, I will need to differentate it too, but and I don't know how to do it either. but for that one, how did they do it?
