Why are the Borel subsets on $\mathbb R$ a $\sigma$-algebra? @vitasoy: You'll need to provide a little more context. We could guess what A.2 and A.3 are, but it would be much better for you to edit the question to include the precise statements you are wondering about. Cheers. |

Why are the Borel subsets on $\mathbb R$ a $\sigma$-algebra? @Rob: I think this question will be closed virtually instantaneously on MathOverflow as off-topic (not research-math level). One might debate whether it is better placed here or on math.SE, though. Right now the question is unanswerable (what is A.2 and A.3?), but it will be a duplicate over there once this is clarified. |

Empirical distribution alternative Fair enough. Thanks for the response. My main point of raising the issue of the sampling scheme was to address the theory, i.e., with (presumably) no extra work to sample as I've described (compared to the scheme you've laid out), one can obtain a more recognizable estimator with behavior that will be (I think) very easy to compare to the empirical distribution function. |

Density of robots doing random walk in an infinite random geometric graph That's true, but I took the sentence to mean what it said: You know there are only $n=1+4t+2(t−1)^2$ possible places you can land on the lattice after $t$ steps. :-) Perhaps an edit would help clarify. Cheers. |

Empirical distribution alternative (...) (ii) with potentially superior properties. (3) I would suggest you consider a little more flexibility with regard to the bounty. You may be surprised at some of the answers you get and awarding it too quickly may stunt that process to a certain degree. |

Empirical distribution alternative I am going to be nitpicky; please take it as a sign of my interest. (1) The expression given for TV is still incorrect. Consider two random variables, one is $\mathcal U(0,1/2)$ and the other is $\mathcal U(1/2,1)$. The TV distance between them is 1 (Choose $C = (0,1/2)$, for example), but your expression yields 1/2. (2) I would really like to know if you are married to the sampling scheme you have described. My last comment asks about an alternate sampling scheme. The purpose is to potentially give you an estimator that is (i) easier to analyze and (...) |

Density of robots doing random walk in an infinite random geometric graph How are you going to be at $(1,0)$ after two steps? (Maybe I'm not understanding the walk you're describing. If I think of the "usual" random walk on $\mathbb Z^2$, i.e., uniform in the four cardinal directions, then, unless I'm mistaken, the answer in my first comment should be correct.) |

How can I predict the odds that a dodgeball team is going to win based on the winning history of its players? Closely related: Measuring individual player effectiveness in 2-player per team sports. Also of interest: How to get started with rating and ranking based on pairwise competition data?. Mild curiosity: (A comment on) When is logistic regression solved in closed form?. Searching for Bradley Terry may yield other useful ideas. Cheers. |

Asymmetric S-shaped function mapping interval $[0, 1]$ to interval $[0, 1]$ Dear @pengsun.thu: I have rejected your proposed edit. I'm not sure whether or not you can see the comment I left when I did so, so let me repeat it here: In lieu of editing the answer, please clarify whether you really intended the function to be concave on $[0,c]$ and convex on $[c,1]$. Such a function will not look much like an $S$ (asymmetric or otherwise). Cheers. :-) |
