 Nov 2 comment Fisher Information for Geometric Distribution Are you sure the answer is correct? In particular, the quadratic $-\frac{1}{\theta^2}$ in the first term of the expectation in line 1 has become $-\frac{1}{\theta}$ in the second line. Oct 10 awarded Yearling Sep 30 awarded Popular Question Sep 28 comment Rejection Sampling From Conditional Distribution In the final equation, is the $K$ necessary? In particular, since $p(x_1)=p(x_1,s)/K$, does the numerator $Kp(x_1)$ reduce to $p(x_1,s)$? Sep 27 comment Rejection Sampling From Conditional Distribution Beautiful, your methodology helped me reason through the process. Sep 27 accepted Rejection Sampling From Conditional Distribution Sep 24 comment Is statistical dependence transitive? The example given in Problem 2 is vacuous since $X_1$ and $X_3$ are the same random variable, which trivially are never independent (unless constant).

This is not a homework problem... Sep 13 comment What does the decomposition, weak union and contraction rule mean for conditional probability and what are their proofs? The proof is incorrect. In particular the statement $(X \perp Y \mid Z) \& (X \perp W \mid Z) \Leftrightarrow (X \perp Y, W \mid Z)$ is false.

However $g:B\to A$ so $g(x), x \in A$ looks incorrect? I think the correct specification would be $g(f(a)) = a$ for $a \in A$ and $f(g(b)) = b$ for $b \in B$.
