Re: Reconstructing Box Plus/Minus

.... Imagine, player X misses a shot, Stevie Adams or Enes Kanter is standing under the basket, they get the offensive rebound and put it back in. In both cases the team has 2 points, but most boxscore models will say that what Kanter and Adams did was worth more because they get credit for both th...

Re: Reconstructing Box Plus/Minus

When your team has missed a shot, you no longer have possession. If you retrieve the O-Reb, you have regained possession. If you then score, you should get credit for both. It's almost like a steal and score, when you neutralize the opponent's possession and also get the points. This is clearly mor...

Re: Reconstructing Box Plus/Minus

I have no hard data to support this, but I've always felt that all the boxscore models overrate players that score a lot of their points off offensive rebounds (typically Cs, but some others). That combination results in both theoretical value (the offensive rebound) and actual value (the player sco...

Re: NBA - DRPM

I'm not looking for information for gambling purposes (though I would not eliminate that possibility if I thought I had a profitable insight). I'm just trying to understand and measure player value better. There are too many things missing from the boxscore and some of the things included are hard t...

NBA - DRPM

How reliable is NBA DRPM at measuring individual defense? I don't want to put too much weight on eye test, but I find too many players I think are clearly good or bad as individual defenders that happen to be on a team that is the opposite of what they are and the team quality seems to get passed to...

Help with Regression Analysis

This is a non basketball question, but it could easily become one in the future because I keep some basketball stats also. I have an Access database of horse racing information that can easily be exported to Excel or other data formats. In the database I have information on thousands of horse races ...

Re: 1952-2014 statistical rankings of 708 NBA/ABA careers

Is there any way you can easily recalculate this but only using the players' best 5 years?

Some players played way past their peak. Others came into the league younger than others. That impacts their overall record.

Re: Wins Produced?!

Player "X" is a C that only takes shots at the rim because he lacks the skill to shoot mid range and further jumpers. Player X hits 65% of his 7 shots at the rim. Player "Y" is a SF that shoots from all over the court (inside, outside, 3 pointers etc..). Player "Y" hits 65% of hits 7 shot at the rim...

Re: Weighting Performances

I'm about to give you a big hug. I just downloaded R, started looking at it, and realized it was going to take me a bit of time to have any idea how to use it. That's a project for another day. There aren't enough ways to thank someone on a forum. Seriously. :D I have to learn how to use that softwa...

Re: Weighting Performances

I must not have been clear. What I want is the weights to use on the first 3 numbers to get as close as possible to the 4th number (which I already know) for a sample of 100 cases. I'll make it simpler and use only 3 numbers and 2 cases. 100, 50, 75. To get a 75, the appropriate weight for the 100 ...
