A fun example I worked out of a situation that is a bit of a problem for frequentist inference (i.e. designed to be compatible with Bayesian inference): http://www.win-vector.com/blog/2014/07/frequenstist-infe

Again disappointed by the traditional meaning-warp mod change of title from the original warning claiming that Flash force installs PlayPanel without notice (something I admit I have not directly confirmed, as I don't intend to risk it

Deviance or log-liklihood are good measures (and when properly normalized give you one of the cross-entropies). Roughly you do -sum(ifelse(rained_i,log(p_i),log(1-p_i)). So you git a high (bad) penalty score if you get wrong probabilities

Numerical near-miss coincidences are to be expected when working with transcendental numbers. First reason is the pigeon hole observation others have made. The other reason is: this is one of the properties of transcendental numbers. Roug

Some historic quick-sort mis-implementations had O(n^2) runtime when trying to sort constant data (all keys equal, the effect was due to not picking the partition carefully in that case). See: http://www.win-vector.com/blog

I love OSX, but the jumping is a very new behavior and the application specific parts of the menu bar aren't even a good idea for large monitors (let alone multiple monitors).

Because the average home consumer doesn't use the feature. Have any of the common OSs does this well (OSX sure didn't, did Linux?)?

I don't get it. DST installs 3 tools: R, Python, and DST itself. R and its packages are VERY easy to install, Python and its packages are pretty easy to install, and you don't need DST until you choose to install DST. It's

I get you. I set the draw probability to as observed, whereas you set the number of draws to as observed. But really I just meant to point out you were right (while giving a simulation that didn't involve explicit conditioning).

The first analysis isn't terrible. It gets the important points right (that the draws are not evidence of difference in skill) and moves on to the remaining evidence (difference in wins to losses). The draws are at best evidence towar

I absolutely love the original analysis (which is why I shared it). The hardware version: anything capable of general purpose work is too important to use- so you delegate to specialized hardware. That hardware then evolves the capability

No, with good fortune the data is directly transcribed by a machine. Babbage included a printer in his designs to avoid human transcription error.

"Manual intervention" would have been better. The steps involved can be copying and pasting, selecting a range (very nasty if you miss and don't notice), and even typing data from another source. Compare that to something l

With spreadsheets a lot of steps needlessly require human transcription (cut/paste, typing and so on). So there is a casual relation.
