I understand the proof except for one part of the forward implication (only if) (https://en.wikipedia.org/wiki/Sufficient_statistic#Another_proof). Specifically, $Since $T$ is a function of $X$, we have $f_{\theta}(x,t) = f_{\theta}(x)$ (only when $t = T(x)$ and zero otherwise) I tried...

Re: UNSW chit chat thread 2017 That's not the point. He knows how to think like a programmer..

Re: UNSW chit chat thread 2017 Looking at his post history, we can tell that he's an avid programmer.

$\noindent Optimise your process with this, $\\ \frac{x+y}{x-y} - \frac{x}{x-y} + \frac{y}{x^2-y^2} =\frac{y}{x-y} + \frac{y}{(x-y)(x+y)}

Some hints. \frac{a}{b} + \frac{b}{a} = \frac{a^2 + b^2}{ab} = \frac{74}{-5} \frac{a}{b} \cdot \frac{b}{a} = 1

Re: UNSW chit chat thread 2017 A genus of domestic cattle.

Although irrelevant, you haven't made it clear on the gender of the 5.2 person. The problem I see is laziness, lack of motivation. Why? It seems that he/she does not care about their education. He/she must identify their goals and you must convince them to add education and education...

Follow-up: with the increase in interest rates, what happens to inflation? Why?

Hints: a) Factor Theorem b) Factor Theorem c) Differentiation and Factor Theorem

Re: International Baccalaureate Marathon No typo, ahah.

Re: International Baccalaureate Marathon I agree that u_n = 4882.8125 yields n = 7, but I'm still confused as to why you tried u_n = 8125.

Re: International Baccalaureate Marathon The last term is 4882.8125 as you have established already, then you got confused and thought that the last term is 8125 because you mis-read the comma (,) as a decimal point (.)

Something good to someone may be bad for someone else. Read the course summary and it's outline (PDF) to see if it qualifies as good to you.
