  2. As I am statistically literate (to a first grade level) but otherwise deficient, may I ask how you determine a constant?

  3. Love me some NERD! “the hardest science available”!!

    I’m just shocked you’re so open with the formula. In 40 years it’ll be the premier stat National Media will care about.

  4. You figure out what number is required to get the 0-10 scale to work. No one likes a scale from -4 to 6.

    Comment by NatsFan73 — April 29, 2013 @ 10:43 am

  5. The constant is the difference between the average of the raw scores and 5.0 — such that, after the constant is added to all the raw scores — the average of all the finished NERD scores 5.0.

    Does that make sense?

    It’s basically whatever number needs to be added to create 5.0 as the average for all the NERD scores.

    Does that make sense this time?

  6. fantastic.. love the NERD

  7. The constant is just to get it to the scale he wants. So instead of the scores being between -4 and 6, he adds a constant of 4 to get it to 0 to 10 (for example).

    It’s like the FIP constant to get FIP in the range of ERA.

  8. For me, personally, Yu Darvish’s NERD score is an 11.
    For several of my female friends, Yu Darvish’s hindquarters are also an 11.

  9. Suprised that nobody got an 11 this time, given the list of pitchers.

  10. Regrettably and with some regret, I haven’t found a way to integrate an assessment of hindquarters into the scores yet.

  11. Happy to see the return of NERD

  12. “Note that Velo and Age are capped at 2.0; Luck, at 1.0. For science reasons.”

    indeed. science.

  13. This is my first season of reading this site daily–I had noticed everyone clamoring for NERD scores but I didn’t bother learning what that was. I must say this is so much grander than I could have imagined. Very impressive science.

  14. Dear Author forgot the intro:
    The rank and qualifications of the writer.

    The scribe of noble parts, patient in discussion, at whose utterances men rejoice when they are heard, skilled in the hieroglyphs; there is nothing he does not know. He is a champion in valour and in the art of Seshyt; servant of the lord of Khmun in the hall of writing; assistant-teacher in the office of writing. First of his companions, foremost of his fellows, prince of his contemporaries, without his peer.

    His merit is proved in every stripling. His hand goes forth, noble, keen of wit, adept in knowledge; fortunate are we because of it. Protecting himself by his good qualities; beloved in men’s hearts, without being repelled; men like to make a friend of him, they do not tire of him. Swift to inscribe empty rolls. Youthful, eminent of charm, pleasant of grace. Unravelling the obscurities of the annals like him who made them. All that goes forth from his mouth is steeped in honey; the heart is refreshed with it as it were with medicine. Groom of his Majesty, follower of the Sovereign, trainer of the steeds of the king, ardent cultivator of the stable.

    He greets his friend, his excellent brother, the royal scribe in command of the victorious army; noble of parts, goodly of qualities, adept in knowledge; who has not his equal in any scribe. Beloved of all men; beautiful to him who beholds his charm; like a flower of the marshes in the heart of others.

    A scribe in every style; there is nothing that he does not know. Men inquire after his response in quest of choice words. Keen of wit, patient of heart, loving mankind; rejoicing at deeds of Justice, he turns his back upon iniquity.

    Carson Harrington Cistulli, son of the steward Philip, the revered.

  15. So glad to see the Dodgers low in the NERD score. I have been to several Dodgers games and watched most on television and boy has this season been boring for them. My Indians though, are near the top, and even though they have struggled it has been a fun season to watch.

  16. I don’t know how open you are to tinkering, but I personally find very old starting pitchers interesting as well — have you considered giving them a positive although not fully-weighted NERD score based on their Age?

    Think for example of late-career Roger Clemens — I saw a game where the Rockies bunted on him excessively so that we could laugh at him trying to run off the mound to field them. That was definitely worth watchability points. Or of one of the numerous Jamie Moyer maybe this will be his farewell tour starts…

  17. Agreed.
    Mr. Cistulli?

  18. I have also requested that slow pitcher PACE ratings be penalized.

    Comment by Well-Beered Englishman — April 29, 2013 @ 3:05 pm

  19. I have to disagree, I don’t find it entertaining to see old pitchers flounder in the field. I want to see pitchers put on a clinic and make the batters look foolish.

  20. Got it guys, thanks.

  21. Can anybody work out when today’s games are scheduled to begin?

    Comment by Klements Sausage — April 29, 2013 @ 5:06 pm

  22. The prospect of three or four Harvey-Stanton confrontations alone should be enough to give the Mets-Marlins game a 10.

    Comment by DavidJ — April 29, 2013 @ 5:24 pm

  23. There MUST be some way to incorporate the announcer data that was calculated last year to come up with an overall GEF (Game Enjoyment Factor).

    Hardest science available… turgid, purple science, in fact. Much like my wife, I love me some NERD.

  24. Wow, first time on the site and my mind is scrambled, can’t wait to learn more

    Comment by Wes Renne — May 25, 2013 @ 7:07 pm

  25. Can you incorporate pitchf/x h- and z-movement numbers for breaking balls into NERD scores?
