Re: "standard error" of OPR values

And regardless I think see the SEs lets us see if a team has a more variable performance than another. That's another piece of information that we can then use to explore it further. For example is the variability arising because parts keep breaking or is there an underlying improvement trend through the competition--either one would increase the SE compared to a steady performance rate. There's other tools for digging into that data, but we may not look unless we have that SE measure first. |

Re: "standard error" of OPR values
Kind of reminds me of a joke I heard this past weekend that was accidentally butchered:
A physicist, engineer and a statistician are out hunting. Suddenly, a deer appears 50 yards away. The physicist does some basic ballistic calculations, assuming a vacuum, lifts his rifle to a specific angle, and shoots. The bullet lands 5 yards short. The engineer adds a fudge factor for air resistance, lifts his rifle slightly higher, and shoots. The bullet lands 5 yards long. The statistician yells "We got him!" ************************************************** ******** A really interesting read into "what is important" from stats in basketball: http://www.nytimes.com/2009/02/15/ma...ewanted=1&_r=0 +/- system is probably the most similar "stat" to OPR utilized in basketball. It is figured a different way, but is a good way of estimating impact from a player vs. just using points/rebounds and.... The article does a really good job of doing some comparison to a metric like that to more typical event driven stats to actual impactful details of a particularly difficult to scout player. I really enjoy the line where it discusses trying to find undervalued mid pack players. Often with scouting, this is exactly what you too are trying to do. Rank the #16-#24 team at an event as accurately as possible in order to help foster your alliances best chance at advancing. If you enjoy this topic, enjoy the article, and have not read Moneyball, it is well worth the read. I enjoyed the movie, but the book is so much better about the details. |

There's an equivalent economists' joke in which trying to feed a group on a desert island ends with "assume a can opener!" ************************************************** ******** Quote:
In baseball, this use of statistics is called "sabremetrics." Bill James is the originator of this method. Last edited by Citrus Dad : 13-05-2015 at 18:41. Reason: added about sabremetrics |

Re: "standard error" of OPR values
hi all,
as a student going into his first year of undergrad this fall, this kind of stuff interests me. what level (or course equivalent or experience of the student) is this kind of stuff typically taught at? I have researched into interpolation, as I would like to spend some time developing spline path generation for auton modes independently, and that particular area requires a bit of knowledge in Linear Algebra, which I will begin the process of self-teaching soon enough. As for this, what would be the equivalent of interpolation:linear algebra? I don't mean to hijack the thread, but it feels like the most appropriate place to ask... |
