Matloff, who has a foot in both the Statistics and CS camps, but says, "The problem is not that CS people are doing Statistics, but rather that they are doing it poorly. Generally the quality of CS work in Stat is weak. It is not a problem of quality of the researchers themselves; indeed, many of them are very highly talented. Instead, there are a number of systemic reasons for this, structural problems with the CS research 'business model'." So, can Statistics be made more attractive to students? "Here is something that actually can be fixed reasonably simply," suggests no-fan-of-TI-83-pocket-calculators-as-a-computational-vehicle Matloff. "If I had my druthers, I would simply ban AP Stat, and actually, I am one of those people who would do away with the entire AP program. Obviously, there are too many deeply entrenched interests for this to happen, but one thing that can be done for AP Stat is to switch its computational vehicle to R."
A complementary analysis of unrelated kids corroborated this conclusion — strangers with equivalent academic abilities shared genetic similarities. What's more, the genes responsible for math and reading ability appear to be numerous and interconnected, not specifically targeted toward one set of skills. These so-called 'generalist genes' act in concert to determine a child's aptitude across multiple disciplines. The finding that one's propensities for math and reading go hand in hand may come as a surprise to many, but it shouldn't. People often feel that they possess skills in only one area simply because they perform slightly worse in the other."
Author John Scalzi says Amazon's reasoning and assumptions are a bit suspect. He disagrees that "books are interchangeable units of entertainment, each equally as salable as the next, and that pricing is the only thing consumers react to." Scalzi also points out that Amazon asserts itself as the only revenue stream for authors, which is not remotely true. "Amazon's assumptions don't include, for example, that publishers and authors might have a legitimate reason for not wanting the gulf between eBook and physical hardcover pricing to be so large that brick and mortar retailers suffer, narrowing the number of venues into which books can sell. Killing off Amazon's competitors is good for Amazon; there's rather less of an argument that it's good for anyone else."
Oddly, only 5% of adults have debt 30-180 days past due. This latter fact is partially accounted for by the fact that a broader range of debt can enter "in collections" status than "past due" status (e.g. parking tickets)... But also perhaps demonstrates that as one falls far enough along the debt spiral, escape becomes impossible. Particularly in the case of high-interest debt such as credit cards — the issuers of which cluster in states such as South Dakota, following a 1978 Supreme Court ruling that found that states' usury laws did not apply to banks headquartered in other states.
Even taking into account the folks who lost a parking ticket under their passenger seat, 35% is a pretty shocking number. Anyone have other theories why this number is so much higher than the 5% of people who are just "late"? How about some napkin math on the debt spiral?
