(author here) Actually I had that wrong. data.table uses its own notation at the command line and switches behavior to imitate data frames in other contexts (such as library) code. I've apologized to the team and retracted the articl

Almost exactly decimation.

The proof is short, but frankly I can't read it (as I am not sure what all the products are sisj ; I presume they are line segments and the + is union/area or some such). Yes, I know it because I didn't study classic geomet

More like: distribution of sales prices fell. I don't think many individual homes sold for less.

There is a technical reason to prefer Mean Square Error derived measures (like RMSE and standard deviation) in some situations (such as machine learning and value estimation): when minimizing one of these measures you tend towards the mean

I agree. In fact I don't think one can succeed in mitigating GC latency unless you understand how very important it can be. The excellent presentation "How NOT to Measure Latency" explains how with the wrong measure latency

I like how they argue it would be less work to patch around the "out of date" message (and then maintain a fork) than to just update XScreenSaver. By Debian logic wouldn't they have to wait forever to take their own patch?

This paper ( http://arxiv.org/pdf/1007.0437v1.pdf ) estimates 11 million years into a 27 million year cycle. So a typical mid-point position (yey!).

Also I bet we are going to find the health statistics of people found to have minor arrhythmia through cheap continuous screening are going to be completely different than those that come in with a complaint and are given a one-time screeni

Don't know the details of LivingSocial, but in general liquidation preferences can complicate it. Instead of 1x or 2x return for all investors it is often 5x for the last investor and 0x for the rest. So it not all investors have a r

Mine was IMSAI 8080. But I had forgotten- I think one of the Star Trek games did the phasers on the radio.

(just skimming) I am guessing the y-axis is the observed expected value of the treatment (low being good) and the dots are re-colered to null if the sample size was too small to separate the (not shown) error bars around the dot from no eff

Neat. In the 1970s there was a program that triggered the S100 bus of the time and played Flight of the Bumble Bee on a nearby radio.

There is a pretty common scam going on on YouTube right now. Make "mix tape" on YouTube of snippets you don't own and then file a copyright claim against anything else on Youtube that matches a segment. Youtube lets the com

I think the broker does make a number of attestations that if not properly done are fraud and render the policy void (as the insurance companies wrote the law).

It is neat- the need to look at the second derivative in "Optimal Brain Damage" (because we know the first derivatives will be zero due to the use of optimization) also underlies Fisher information https://en.wikipedia.

You can try Postgres "zero install" with Postgres.app for OSX, otherwise docker. http://www.win-vector.com/blog/2016/02/databases-in-containe...

I use a bit less of the Hadleyverse than my colleagues like. But ggplot2 has a number of advantages over base graphics (even if you were to figure out base graphics). One being the plot is a structure or value (returned by plot constructi
