Nate Silver and college football

I thought Nate Silver only looked at professional sports. I was wrong – here is a cool interactive web page he has put together for college football. The numbers don’t always give you the answers you want to hear though – even if my beloved Gators somehow win all the rest of their games, which would include beating Alabama in the conference championship game, he gives them only a 13% chance of winning the national championship. Another nice thing about Nate Silver – he always explains his methodology.

We’ll be updating the numbers twice weekly: first, on Sunday morning (or very late Saturday evening) after the week’s games are complete; and second, on Tuesday evening after the new committee rankings come out. In addition to a probabilistic estimate of each team’s chances of winning its conference, making the playoff, and winning the national championship, we’ll also list three inputs to the model: their current committee ranking, FPI, and Elo. Let me explain the role that each of these play…

FPI is ESPN’s Football Power Index. We consider it the best predictor of future college games so that’s the role it plays in the model: if we say Team A has a 72 percent chance of beating Team B, that prediction is derived from FPI. Technically speaking, we’re using a simplified version of FPI that accounts for only each team’s current rating and home field advantage; the FPI-based predictons you see on ESPN.com may differ slightly because they also account for travel distance and days of rest…

Our college football Elo ratings are a little different, however. Instead of being designed to maximize predictive accuracy — we have FPI for that — they’re designed to mimic how humans rank the teams instead.4 Their parameters are set so as to place a lot of emphasis on strength of schedule and especially on recent “big wins,” because that’s what human voters have historically done too. They aren’t very forgiving of losses, conversely, even if they came by a narrow margin under tough circumstances. And they assume that, instead of everyone starting with a truly blank slate, human beings look a little bit at how a team fared in previous seasons. Alabama is more likely to get the benefit of the doubt than Vanderbilt, for example, other factors held equal.

R code to read Nate Silver’s data

Thanks to Nate Silver for posting all his polling data in a convenient text file that anyone can read! It’s a nice thing to do. Even though not many of us can do as interesting things with it as Nate Silver, it is a fun data set to play and practice with. Here is an R-bloggers post with some ideas on how to play with it.

3 most frightening stories

  • The U.S. electric grid is being systematically probed by hackers working for foreign governments.
  • According to James Hansen, the world needs “negative” greenhouse gas emissions right away, meaning an end to fossil fuel burning and improvements to agriculture, forestry, and soil conservation practices to absorb carbon. Part of the current problem is unexpected and unexplained increases in methane concentrations in the atmosphere.
  • The epidemics that devastated native Americans after European arrival were truly some of the most horrific events in history, and a cautionary tale for the future.

3 most hopeful stories

  • New technology can read your heartbeat by bouncing a wireless signal off you. Mark Zuckerberg has decided to end disease.
  • While he still has people’s attention, Obama has been talking about Mars and zoning. Elon Musk wants to be the one to take you and your stuff to Mars.
  • Maine is taking a look at ranked choice voting. Ironically, the referendum will require approval by a simple majority of voters. Which makes you wonder if there are multiple voting options that could be considered and, I don’t know, perhaps ranked somehow? What is the fairest system of voting on what is the fairest system of voting?

the smart grid

Stanford has a research project for the smart grid.

Bits & Watts is a major new Stanford/SLAC initiative focused on innovations for the 21st century electric grid—a new grid paradigm that is needed to incorporate large amounts of clean power and a growing number of distributed energy resources, while simultaneously enabling grid reliability, resilience, security, and affordability.

The initiative organizes its research into three thematic areas: grid core, grid edge, and grid data science. The initiative will advance technologies, policies, markets, regulations, and business models that work in concert between each thematic area.

The Bits & Watts Initiative seeks to:

  • Offer and implement new research ideas and de-risk them for the electricity ecosystem
  • Educate faculty, students, post-doctoral fellows, and staff about the holistic systems-focused approach to solving problems for the electricity ecosystem
  • Offer holistic educational experience for current industry executives and other leaders
  • Create open-source hardware and software solutions rapidly adopted by industry and policymakers
  • Maintain flexibility amid uncertainty to exploit emerging technologies
  • Be a trusted and unbiased convener
  • Create platforms and protocols for sharing data with due consideration of privacy, security and confidentiality

ranked choice voting

Larry Diamond on BillMoyers.com talks about a referendum in Maine that could lead to ranked-choice voting being used in that state in the future. The basic idea is that if no candidate gets a majority of first-place votes on the first ballot, then votes from the lower-ranked candidates get redistributed based on how people ranked all the candidates. Ultimately, this results in a winner who is acceptable to a majority of the voters even though they may not have been the top choice of a plurality of voters. This could encourage a Bernie Sanders or Ralph Nader (or Ross Perot or future Donald Trump) to run as a third-party candidate rather than competing for a major-party nomination.

…the issue at stake in Question 5 (a citizen-initiated referendum) is whether Maine will adopt a system called ranked-choice voting (RCV) in all its elections. If they approve the measure, Maine voters will have a unique opportunity to showcase the transformative potential of US democracy and to send a much-needed signal for reform at a crucial moment.

In RCV, voters select not just one candidate, but a list of candidates in order of preference. If no candidate gets a majority of first-preference votes when tabulating the results, the least popular candidate is eliminated and the second-preference votes of his or her supporters are redistributed to the other candidates. The process continues until someone gets a majority.

The ability to rank all the candidates running for office, rather than voting for only one, is intrinsically more democratic. But, because it forces candidates to try to appeal to a broader cross-section of the public, RCV also makes it much more likely that the winner will be open to moderation, compromise and building governing coalitions…

How often do we have a Presidential winner who did not get a majority of the popular vote? George W. Bush and Bill Clinton are the obvious examples from my lifetime, but it has happened before. This article on History News Network answers the question.

Seven of the Presidents who won without a majority were Democrats—Polk, Buchanan, Cleveland both times, Wilson both times, Truman, Kennedy, and Clinton both times. Six of the Presidents who won without a majority were Republicans—Lincoln, Hayes, Garfield, Benjamin Harrison, Nixon, and George W. Bush. One Whig, Zachary Taylor, and one Democratic-Republican, John Quincy Adams, finish the list.

giants of Cold War era nuclear strategy

This New York Times Book Review article goes through some of the key architects of Cold War era nuclear strategy.

The theories of Cold War defense intellectuals now seem the stuff of a surreal madness that seized Washington during the last half of the 20th century. The core doctrine of nuclear deterrence was Mutual Assured Destruction, aptly known as MAD. It postulated that the best way to prevent a nuclear war with the Kremlin was to build an enormous atomic arsenal that would annihilate the Soviet Union if it dared attack the United States. Effective, yes, but a White House or Kremlin miscalculation would have left millions dead, nations destroyed and the planet reeling.

Albert Wohlstetter, an analyst at the RAND Corporation, was one of the most formidable of the nuclear policy savants. A combative champion of defense spending, he argued that the balance of terror inherent in MAD was unstable. Instead of assuming the MAD standoff would assure a durable cold peace, he feared a Pearl Harbor-like Soviet attack outside the imagined scenarios of defense planners, and he pressed for a nuclear war-winning policy. His ideas coursed through American defense strategy for decades, swaying presidents, attracting acolytes, infuriating opponents and igniting furious debates that ricochet through official circles to this day…

Robin, president of the University of Haifa in Israel, recalls many of the thinkers and baroque theories of the nuclear age. Some attracted national attention at midcentury, including Henry Kissinger, whose 1957 book, “Nuclear Weapons and Foreign Policy,” became an unexpected best seller, and Herman Kahn, whose chilling ruminations on winning and surviving a nuclear conflict made him an oracle of the unthinkable. Bernard Brodie, the intellectual father of nuclear deterrence theory, played a pivotal role in shaping Cold War nuclear policy.

civilians in Mosul

The United States and Iraq are planning a major offensive against ISIS in Mosul Iraq. This description in The Week about what is expected to happen to civilians is a bit shocking. If we are doing this to keep civilians from being oppressed, is it really worth it?

About 4,000 Kurdish peshmerga are fighting to retake a string of ISIS-held villages east of Mosul, with support from U.S. warplanes, artillery, and special operations commandos. The main attack is being launched from Qayyarah air base, some 40 miles south of Mosul, where 560 U.S. military advisers, 22,000 Iraqi government troops, and 6,000 mainly Sunni tribal fighters have gathered in recent months. Backed by coalition air support, liberation forces will advance along the Tigris River, clearing ISIS from towns and villages before reaching the city’s edge in early November. Experts say the main urban battle will probably last through December. Much of the battle could be fought street to street and house to house — the winding, narrow streets of Mosul’s Old City are inaccessible to tanks or artillery…

Its [ISIS’s] roughly 5,000 fighters in the city have spent months creating an elaborate network of defenses. IEDs have been hidden underneath roads and in buildings, and five bridges have been rigged with explosives. Residents told Reuters that a 6-foot-wide, 6-foot-deep moat has been dug around Mosul’s perimeter, which will be filled with oil and set on fire, creating plumes of smoke to make it difficult for warplanes to spot targets. To evade airstrikes, ISIS is funneling men and equipment through underground tunnels. Former Iraqi finance and foreign minister Hoshiyar Zebari says militants are “shaving their beards to blend in with the population and constantly moving their headquarters around.” The jihadists are desperately trying to boost their numbers: Local men who refuse to take up arms have had their ears cut off, and locals say children as young as 8 have been handed pistols and knives and ordered to spy on citizens…

Relief agencies say the battle for Mosul will trigger a mass exodus: Many of the city’s remaining residents are expected to flee at once, leaving their possessions behind. “We’re facing this enormous tsunami coming at us,” says Lise Grande, the United Nations humanitarian coordinator for Iraq. Coalition forces will have to screen out jihadists from the refugees, and, with some 3.3 million Iraqis already displaced by violence, overstretched aid agencies will struggle to feed and house all of Mosul’s desperate civilians. Says Matthew Nowery of U.S. relief group Samaritan’s Purse, “This is going to be a very large-scale catastrophe.”

So is it worth it? This made my think of Obama’s Nobel speech, where he argues that there is such a thing as “just war”.

And over time, as codes of law sought to control violence within groups, so did philosophers and clerics and statesmen seek to regulate the destructive power of war.  The concept of a “just war” emerged, suggesting that war is justified only when certain conditions were met:  if it is waged as a last resort or in self-defense; if the force used is proportional; and if, whenever possible, civilians are spared from violence.

Of course, we know that for most of history, this concept of “just war” was rarely observed.  The capacity of human beings to think up new ways to kill one another proved inexhaustible, as did our capacity to exempt from mercy those who look different or pray to a different God.  Wars between armies gave way to wars between nations — total wars in which the distinction between combatant and civilian became blurred.  In the span of 30 years, such carnage would twice engulf this continent.  And while it’s hard to conceive of a cause more just than the defeat of the Third Reich and the Axis powers, World War II was a conflict in which the total number of civilians who died exceeded the number of soldiers who perished…

Moreover, wars between nations have increasingly given way to wars within nations.  The resurgence of ethnic or sectarian conflicts; the growth of secessionist movements, insurgencies, and failed states — all these things have increasingly trapped civilians in unending chaos.  In today’s wars, many more civilians are killed than soldiers; the seeds of future conflict are sown, economies are wrecked, civil societies torn asunder, refugees amassed, children scarred.

It also reminded me of Human Smoke, where Nicholson Baker puts forth the heretical view that the human cost of the fight against the Third Reich and the Axis powers itself may have exceeded its benefit.

insurance and smart homes

According to MIT Technology Review, some insurance companies are giving discounts for smart devices.

Insurers across the U.S. are offering incentives to install one of half a dozen connected devices, ranging from moisture sensors to video doorbells. State Farm offers a discount on your home policy for installing a Canary home security monitor, for example. Liberty Mutual will send you a Nest Protect smoke detector, worth $99, free of charge and cut the cost of fire coverage.
