While implementing a quick toy example of Crane and Sawhney's really great Monte Carlo Geometry Processing paper, the question arose about whether a quick function I grabbed from The Internet to equally distribute points on a sphere was correct or not. Since it's absolutely the crux of the method, this is an important question! This notebook performs a rather unscientific check for equal distribution of points on the surface of a sphere. It uses the first algorithm from MathWorld

Black Harvard economics professor wrote a research paper investigating whether racial differences in police shooting rates were the result of “racial bias” or “statistical discrimination”. Statistical discrimination = an individual or institution treats people differently based on data that reflects the average behavior of a racial group. Racial bias = if police pull over black drivers at a rate that disproportionately exceeded their likelihood of drug possession, that would be an irrational behavior representing individual or institutional bias.
Jewish Harvard Health & Human Rights Fellow finds flaws in methodology, but also shows extreme lack of neutrality to social science research! These are two of his opening statements: 1. "There should be no argument that black and Latino people in Houston are much more likely to be shot by police compared to whites." 2. "the idea of “statistical discrimination” is just as abhorrent as “racial bias”."
Methodological flaw one seems valid.
1. pulling people over who are most likely to have done something illegal, and making more arrests is rational behavior by police. It isn't the right approach to shootings though, as police officers are not trying to rationally maximize the number of shootings.
2. flaw two is described as this: actual study assumes a population of people who are shot by police OR people who are arrested. Proper approach is to assume a population of drivers stopped by police that can have one of two outcomes: they can be arrested, or not. This is a less valid criticism, because "proper approach" doesn't even have shooting as an outcome! Finding is that of the two groups (shot OR arrested), racial disparity in arrest rates is larger than the racial disparity in police shooting.
Let’s imagine a hypothetical situation. There’s an infection going round, and we want to predict the future severity of someone’s illness. There is a test that offers a good prediction. Let’s say the outcome of the test has a correlation of 0.78 with the patient's severity of infection. The problem with the test is that…

Survey responses reveal that beyond lack of journal access, convenience and antipathy toward publishers are key motivations for turning to paper repository By John TRavis, May 2016
I've spent the last few months preparing for and applying for data science jobs. It's possible the data science world may reject me and my lack of both experience and a credential above a bachelors degree, in which case I'll do something else. Regardless of what lies in store for my future, I think I've…

84 % suomalaisista kannattaa Suomen liittymistä YK:n ydinaseet kieltävään sopimukseen, käy ilmi ICAN Finland -verkoston Kantarilla teettämästä mielipidekyselystä. Kyselyssä edustavalle otokselle (N = 1002) esitettiin kaksi kysymystä, joista ensimmäisessä kartoitettiin kannatusta ydinaseiden kieltämiselle ja toisessa näkemyksiä Suomen kantaan YK:n ydinasekieltosopimuksesta.
Kysymykseen ”Kannatatteko kaikkien ydinaseiden täydellistä kieltämistä?” vastasi Kyllä 87 %, Ei 8 % ja Ei osaa sanoa 5 % vastaajista.
Kysymykseen ”Pitäisikö teidän mielestänne Suomen allekirjoittaa YK:n ydinaseet kieltävä sopimus?” vastasi Kyllä 84%, Ei 8% ja Ei osaa sanoa 8% vastaajista.
