It's that time again, post your math questions and problems and discuss math in general. Also, post your finals

okay
X1, ..., Xn all have the following pdf
f(xi) = r/theta x^(r-1) e^((x^r)/theta) x > 0
0 ow

just finished up a intro linear algebra final
went the whole semester without studying as a challenge
i think i did pretty well, but i'm fairly certain i missed one

find the likely hood and log likelyhood functions and use those to find a sufficient statistic, the cramer rao lower bound, and an MLE estimator for theta

Someone please!! Help me proof that every subgroup of a free group is free

I think that's called being an idiot.

i already had experience with linear algebra [blog] because i got into graphics programming when i was young and ended up really liking linear algebra [/blog]
unless i totally bombed the final, i'm positive i made an A
and it was a lot of fun

i hate that feel...had a topology final a few days ago that only had formulaic proofs we had done before. i need to study topology over the break to make up for it

I know that feeling.

the exam paper isn't where you're supposed to be developing skills though
hard, interesting problems should go on problem sets where you actually have the time and desire to think about them

accurate.
