Can you ELI5 this sentence. I don't understand it despite staring at it for a while.

There could be, but why do you assume this is do to racial bias as opposed to the unfortunate fact that black people are more likely to commit violent crime? I assume that arrest rates should be a good proxy for police interaction, this is

A study from the NYT addresses this, and finds that if arrest rates is a good proxy for police interactions (a reasonable assumption) the data supports the theory that the reason black people are more likely to be killed by police is becaus

One of my biggest frustrations with python for data science is how bad the documentation for matplotlib is. Also the default settings leave a lot to be desired - look at the color map scatter plots to see what I mean. What is with all that

As a strong chess player (around 2000 blitz on chess.com) I find it very surprising that time was not the most important factor. I know from experience when you get to under 1 second per move remaining the probability of blundering goes way

Take the job - the company offering you the job knows better than you do whether or not you are qualified for that specific job.

This sentiment is not correct - causal explanations do matter. The statistical evidence for global warming is not particularly strong, as temperature data is very noisy. If we didn't have a causal explanation there would not be a scien

I can only speak to particle physics, but the main issue is that we can't study the truly interesting problems. Theories such as string theory are basically beyond the reach of experiments. Our current models work very well to describe

Physicists have a better understanding of statistics and better data to work with than pyschologists. There is a very clear causal explanation for why greenhouse gases do what they do. With that said, there is not enough discussion about th

If the data is truly biased in that it doesn't reflect reality then sure, go ahead and correct for this bias. But make sure you are not introducing your own biases which are wrong. "But is it OK that we’re using extraordinarily bi

The algorithm just tries to model the world as it actually is, not as it is supposed to be. The algorithm cares nothing about uncomfortable truths. The algorithm should not be set up and trained to reflect a wrong model of reality, but rath

This proposal shows more concern about being politically correct than actually correct. A truly unbiased system would just make the best analysis possible given the data available. What you propose is to make a biased system in order to giv

> Until we have better software we’re unable to build good models from small datasets. (And when I say “small” I mean, not ginormous.) This is completely wrong - to build a useful model your model just needs to be able to distinguish bet

I agree with this. There has to be some balance - it is not like EU membership lifts the economies that enter it, so it doesn't seem like it should be so bad to leave the EU. I also expect people to overstate the effects - like currenc

It looks like the average was around 35%: http://predictwise.com/politics/uk-politics Interestingly the odds went down pretty sharply as the election came closer, but it is not really fair to pick the lowest odds when

The betting markets had somewhere around a 35% of Brexit. So it wasn't that unlikely according to the betting markets.

There is pretty conclusive evidence that taller men are on average more attractive than shorter men. However being more attractive does not necessarily mean you will have more kids. My theory is that people want to marry people of similar a

You could absolutely learn all the skills and knowledge to be a good data scientist, the real question is if you could get hired. I have been looking into data science and I think the demand for data scientists is not as large as it seems,

The startup scene is primarily young, white and male. It isn't all that surprising that Trump has support among the startup scene. American tech workers are also particularly vulnerable to outsourcing and have suffered from the H1B pro

"But he has no serious plan for how to restore economic growth, which is what we actually need." The president can't just wave a magic wand and restore economic growth. And just because Trump may well be racist, that does not

The whole premise was based on the assumption that meritocracy is bad - my point is that this is a flawed assumption. The proposed solutions were the government could step in and "discourage hiring practices that arbitrarily and counte

I don't have any problems with a society that is a meritocracy. This article is nonsense. If anyone wonders why so many people don't like political correctness just point them to this article.

It is interesting how different fields have different terms for statistics concepts. Statistics really should be taught at the high school level, it is far more useful than for instance calculus. I hadn't heard those terms before. In p
