Best website to access advanced statistics?

[Bensational]

does anyone know if there's a measurement for the overall success of a PG-C/PF combo? as in, something to find the best PG to partner with a dominant big man?

thanks for all the great mentions so far, I use many of them. From a fantasy stats perspective, is there anything quite like basketballmonster.com?

What is the best stat to determine a player's defensive impact? I don't like stats that incorporate blocks and steals, and would prefer something focused on the offensive production of the player he is guarding. I realize this is difficult though as zone defenses and picks reduce the clarity of which player is responsible for guarding which player. I would think that, as a result, we would be regulating to looking at team defensive statistics with a player on and off the floor. However, the advanced stats on nba.com due break out an individual players performance against another individual, player, so it seems possible to individualize the impact of a single player. I just can't find anything that quantifies how well a player does at holding other players below their average FG% or EFG% for example. Any thoughts on the best means of determining individual defensive impact?

Defense RAPM.

^How exactly is that calculated? And is there only RAPM stats for this year?

Do you want "exactly" or "kinda sorta"? I gave the "kinda sorta" answer in my primer (towards the end):

http://www.d3coder.com/thecity/advanced-stats-primer/

It's a regularized version of adjusted +/- (APM). Basically, it decreases the variance of predictions that you would make with APM, which results in a lower overall prediction error.

Those RAPM ratings I linked to are a weighted multi-year result. Here are the single-year 2012 results:

I'm also calculating adjusted four-factor +/-, which is another way to do it:

^How exactly does it decrease the variance? What happens to the stat/whats added to make it better than regular APM?

Also, thats a great blog. I read a whole bunch of posts you made, it's great work.

For anyone...I'm looking for a stat, basically, I'm wondering for each turnover, how often does it lead to a fast break basket attempt. So for each turnover, how often does the other team get out on the fast break and attempt a shot? I can't find it.

^How exactly does it decrease the variance? What happens to the stat/whats added to make it better than regular APM?

As part of the regression a Lagrange multiplier ("lambda") is added as a penalty term to shrink variance. The value of "lambda" is chosen through cross-validation to minimize prediction error. It's really very common now:

Thank you... For some reason I never knew you could find play-by-play data on basketball-reference !

I've always wondered, how do these stat guys compile all of the statistics onto one spreadsheet/data set to be able to analyse/compare?

I've got some good knowledge of SPSS, Excel, SAS... Learning R currently.. But the actual retrieving of the data has always eluded me..

The RAPM is enlightening, but I'd also like to know how they determine Defensive Ratings for individual players. I can find plenty on how it is calculated for teams, but not for individuals. I appreciate any help. Thanks!

If you are able to program with IBM SPSS and SAS you are on the forefront of what teams are looking for, however it has been my dealing that truly understanding the mission one is trying to accomplish and how to throw out good stats from misleading ones is truly the highest prize.
Excel is nice because its compartments allow for easy brain memory, the problem is many times it is a computer RAM hog and the program itself seems limited once you enter a good amount of data.
