comment Technicality: convergent sequence is preserved by continuous map
Ah, I see. I had a hunch that's what was happening. So if there were not some point satisfying that, then the statement would be vacuously true. In other words, if those points did not exist, then the function would be "trivially" continuous?

I take it you meant $\gamma>0$?

Technically speaking the $z$- and $t$-tests are both parametric tests because they assume the underlying data are drawn from a Normal distribution...

It shouldn't be, in general. Assume $\sigma(X)$ is any non-trivial $\sigma$-field, and let $\sigma(Y)$ be the trivial $\sigma$-field so that $Y$ is constant. Then...

comment Confidence intervals and dividing by $n^{0.5}$
Although I think I understand what you are getting at, you might want to be more specific with exactly where you are dividing by $\sqrt{n}$ in the context of confidence intervals...

comment Triangular tiling of hyperbolic plane
Thanks for your very helpful comments! I edited my original post above to add some explicit forms for $a$ and $b$ that Kleinberg had in the paper. My main point of confusion was the ideal triangle aspect. Am I correct in saying that he (more or less) should've been speaking of the ideal triangle $\Delta = (-1, 1, i)$ instead of the semi-ideal triangle $(0,1,i)$? Given his expression for $b$, it doesn't seem like $b$ permutes the vertices of $\Delta$ unless $\Delta$ is given in this way.
