I downloaded the HTML of the page. Out in the middle of the text is a really simple version of the full list easy to work with in an editor. I got a list of the PDFs I'd like (basically nearly all the analysis and applied math and ne

That the K-S test works is some cute math by the father of modern probability A. N. Kolmogorov. But that test and many more are part of non-parametric , that is, distribution-free hypothesis testing. That statistics has long been popu

Nicely done. There is an important point that the article makes although only implicitly: If have some data and want to know what the probability distribution is, then hopefully know enough good things about where the data came from basica

The remark on selling, suggesting that selling can't be taught, was not right: E.g., I have an uncle who taught his sons selling, right, not for, say, P&G, GE, GF, UGE, IBM, but for his own business. The son's business? Priva

Yup. But in the Manhattan Project, the Ph.D.'s seemed to get that experience quickly enough. Besides, where to find people with experience turning chemical goo into blocks of explosive and machining them to fit precisely in a 3D pu

I see a pattern in the article. The pattern seems to apply to the writers of the article and also Khosla and his firm. The pattern: Hover about 100,000 feet above reality where really can't tell the difference between a horse, cow, o

In short: In some important uses of statistical model building, traditional regression analysis doesn't work or fit very well. One of the reasons to use regression was to look at the regression coefficients as guides to the importa

Just routine conditional expectation. For random variables X and Y (under very meager assumptions, E[X|Y] is the almost sure unique random variable that integrates like X over all events in the sigma algebra generated by Y. In particular

alpha is a number. Type I error is an event.

Each of 0.32 and 0.001 is the conditional probability of type I error conditioned on the data actually used in finding it. It is common to play fast and loose when are conditioning on something and when not. This conditional probability

Okay, I looked at that PDF. I read through several pages and mostly saw lots of discussion of statements the authors claimed were common and wrong. I can agree with the wrong but am less convinced about the common. I never saw a clean def

How about: The p-value is, in a statistical hypothesis test, the probability of Type I error, that is the probability of rejecting the null hypothesis when it is true. Or, suppose we have some data and want to use it to estimate the value

Good thoughts. Thanks. Two questions: (1) IIRC, some operating systems, seeing some ECC errors, maybe just the uncorrectable ones or maybe also the correctable ones, moved to mark the associated memory, or block of memory, as faulty, may

For such a problem, usually "at random" means a uniform distribution. But on the plane, there is no uniform distribution. So, the "paper" can't be the plane. So, it might be fair to ask the size of the paper and w

Of course there are answers: ISIS just attacked NATO -- definitely Darwin award material. NATO can "wipe the desert clean" in less than an hour anytime NATO is willing to do what ISIS does -- create civilian casualties. By cle

Interesting article. Here's why the ISIS plans won't work as the article describes how ISIS is planning: ISIS has basically five things going for them: (1) A lot of oil money, (2) a lot of desert no one wants to try to live in, (3

Data? Code? I vote for engineering and, there, sometimes applied math. E.g., once some colleagues and I gave a paper at an AAAI IAAI conference at Stanford. All the good work was just engineering. For our work, basically just some code,
