Pre-season playoff picks – How did I do?

I went back to my 2014 NFL season preview to check out my playoff predictions.  I did very well in the AFC getting 5 out of the 6 playoff teams correct (I missed the Colts).  Along with this, I got the 1 and 2 seeds exactly correct.  In the NFC, I only got 3 out of the 6 playoff teams (Green Bay, Seattle, and Detroit).  I had picked San Francisco, New Orleans, and Philadelphia to make the playoffs, but they all missed.  Further, I had picked San Francisco and New Orleans to be my top 2 seeds.  In the NFC, the only seed I correctly identified was the Lions at the 6 seed.

So overall, I got 8 out of the 12 playoff teams correct.  Not bad.  imho.

Below are my playoff predictions along with the actual results in parenthesis.

Predictions:

AFC

1. New England (1 seed)

2. Denver (2 seed)

3. Houston (Missed Playoffs)

4. Baltimore (6 seed)

5. Pittsburgh (3 seed)

6. Cincinnati (5 seed)

NFC

1. San Francisco (Missed Playoffs)

2. New Orleans (Missed Playoffs)

3. Green Bay (2 seed)

4. Philadelphia (Missed Playoffs)

5. Seattle (1 seed)

6. Detroit (6 seed)

Cheers!

A false choice #allLivesMatter

This has nothing to do with statistics, but I’ve been reading so much about it lately I wanted to post something.

One thing that I have found odd in the Michael Brown/Eric Garner protests is that it seems many people seem to think that you’re either for the police or against them.  But it’s a choice that doesn’t need to be made.  I’d write more, but what I mean is said better in this article: The Importance of Treating NYPD Officers as Individuals.  And the quote below from that article sums up how I feel:

That intense anger over such videos coincides with persistent rarity of politically motivated attacks on cops underscores Radley Balko’s observation that “it’s possible to both be appalled by senseless executions of cops and angry at unjustified killings by cops.” Those positions are not in tension with one another. They are both consistent the with individualist premise that all lives are valuable, as well as the belief that both police and non-police should act lawfully and justly.

What is the definition of privacy?

The Atlantic has an article posted on its site today entitled “By 2025, the Definition of ‘Privacy’ Will Have Changed“.  This got me thinking again (and I’ve thought about it quite a bit) about just what is a reasonable definition of privacy?  My two major conclusions to that question are that 1) it’s very complicated and 2) it depends.

A simple definition of privacy used in [1] attributed to Professor Weston of Columbia University is

the right “to determine what information about ourselves we will share with others.”

In terms of directly opting in or out of some data collection process, this is a straight forward definition.  However, it’s not always this simple.  For starters, I may want to share my data with organization X but I don’t want to share that same information with organization Y.  So for starters, I would extend this definition to say something like: the right to determine what pieces of information about ourselves we are willing to share and with who.  

Using this definition, someone now would have control over what data they are willing to share and what organizations they are willing to share it with.  Ok easy right?

Well what about this scenario: You are in a class with three students.  You all take a test, and after the test the professor hands back your exam with your grade and tells the class the average test score.  If any two of the three students collude and share their test scores, they can immediately calculate the third students exact score.  I would argue that this is clearly a violation of the third students privacy.  They never willingly shared their exam score with the two other colluding students.  But a piece of information about them was learned.

However, what about situations where the third students score is learned within some range.  Clearly, if you know the students score is between 0 and 100, their privacy is not violated.  But what if you learn that their score was between 80 and 85?  above 50? or less than 70?  Is learning any of these pieces of information a violation of privacy?  I don’t know.  Defining privacy is hard.

The other aspect of defining privacy that I find fascinating is that privacy is not tied directly to a piece of information.  It’s often about HOW that information was obtained.  For instance, if a friend tells me that they have cancer, that is not a violation of privacy.  However, if the hospital without the consent of my friend, discloses that my friend has cancer, a clear violation of privacy has occurred.  EVEN if I already knew that the friend had cancer.  So it’s not the information itself that causes a privacy problem, it is a combination of the data AND the mode of transmission.  (Another random question: Is it a privacy violation for a hospital to confirm that you do NOT have cancer?  I would argue yes.)

My point here is that privacy is a very slippery concept and difficult to pin down an exact definition of.  But studying and learning about privacy is going to be an increasingly valuable topic as data about ourselves is being collected on such a monumental scale that it would have been hard to imagine this even ten years ago.  Try to imagine what this will be like in another 10 year?  or 25 year?  or 50 years?

Finally, I especially like (and am terrified by) this quote from the last paragraph of that article:

We are embarked, irreversibly, I suspect, upon a trajectory toward a world in which those spaces, times, and spheres of activity free from data collection and monitoring will, for all practical purposes, disappear.

Cheers!

An NHL shootout lasted 20 rounds. How improbable was it

statsbylopez's avatarStatsbyLopez

Tonight’s Panthers/Capitals game lasted an improbable 20 rounds, with the teams recording the following round by round outcomes (X for misses, 0 for goals)

Washington: X X X O X X O X X O O X X X X X O X X X

Florida: X X X O X X O X X O O X X X X X O X X O

Estimating the likelihood of a shootout reaching 20 rounds is actually fairly straightforward, provided that you make some reasonable assumptions.

Assumption 1: The save percentage for each goalie is 67%.

For starters, the overall NHL save rate on shootouts is about 67%. And while I have made the point that not all NHL goalies are created equal in terms of stopping shootout attempts, in this game, both Florida goalie Roberto Luongo (67.3% save rate) and Washington counterpart Braden Holtby (66.0%) are nearly identical to…
