Re: Has anyone looked at team USG% trends close + late?

Hey, look: Tom Haberstroh is all over the Grizzlies' consistent clutch success. http://www.espn.com/nba/story/_/id/18272691/memphis-grizzlies-most-clutch-team-nba Some interesting stuff happening in Memphis. Meanwhile, all my old sheets are corrupt, so I gotta relearn how to scrape NBA.com to do thi...

Re: Has anyone looked at team USG% trends close + late?

In the last few years, a rough glance says the Grizzlies have clearly outperformed NetRtg in, let me see... 2016-17, 2015-'16 and 2013-'14... yeah, it might be luck, but it might also point to something the team does that makes it perform well in situations that are coinflips for other teams... the...

Re: Has anyone looked at team USG% trends close + late?

you're talking about a team that is 18-9 but with the average per game point differential (+0.1 pts/g) of a team that historically has played close to .500 ball... they are 1st in the league in defensive efficiency, but 3rd worst in offensive efficiency... they've won 4 OT games and another 3 games...

Has anyone looked at team USG% trends close + late?

Looking at Memphis' consistently ridiculous record in close games (with Conley injured this year) has me thinking if missing the team's primary ballhandler in close + late situations might actually be a stealth advantage? So far, I have done no work on it, but my thinking would be this: Intuitively,...

Re: How do I measure noise?

What you need, Ed, is to do year-to-year correlations and then back out how much noise there is vs. how much signal. Here's one method: http://blog.philbirnbaum.com/2011/08/tango-method-of-regression-to-mean-kind.html Alternatively, you could do a simple regression to predict year 2 from year 1, an...

Re: How do I measure noise?

Are there any tools for dealing with data or statistics that you're familiar with already? You can find lots of stuff for doing regressions using R (which is a tool used for doing statistics). If you run a regression you can check the http://en.wikipedia.org/wiki/Coefficient_of_determination or som...

How do I measure noise?

So, I want to revisit the question of measuring noise in a dataset. This is related to my project looking at productivity based on in-game splits, but I figure this is worth asking in a new thread. I formulas that tell me how much players increase or decrease their rate of recording box score stats ...

Re: Box score stats vs. expected, by in-game situation

One last demonstration before I do a full treatment of close score situations. This is a simple Tableau of the data plotting Shots vs. Expected with Assists vs. Expected in a scatter chart. Here's the combined data from 1996 to present: https://public.tableau.com/shared/MBG6B5KTF?:display_count=yes ...

Re: Box score stats vs. expected, by in-game situation

It came up in the another thread, but since you have split data can you easily test the correlation of second half true shooting with first half usage? I don't have per game data, just full-season data with splits by score. So, if you mean "can I correlate how first half usage affects second h...

Re: Box score stats vs. expected, by in-game situation

Very interesting stuff Ed. Can you define what a "comeback" situation is? Is it whenever the team is trailing? Or only when they trail but ultimately win? Or only when trailing by a certain amount? A "comeback" for the purpose of these stats is any score in which a team isn't wi...

Box score stats vs. expected, by in-game situation

I had a lot of fun with this: I've been working with a database of player in-game splits going back to 1996-97 that I pulled from NBA.com. It’s a big database. I've been using it to try and figure out ways to analyze player mentality by game situation. Basically, I want to show how players change th...

Re: Situational change in attempt/ assist rate

You're into some interesting stuff here. When players don't like to shoot, or don't shoot well, when behind, are they also less likely to do well in close games? You have trouble with <= data for players with good teams; but when these teams get to the playoffs, they're less "good". I won...

Re: Situational change in attempt/ assist rate

Ok, I'm shelving the question of noise for now. Playing with the full dataset I think the shooting data shows clear validity. I'm much less certain about the assist and rebounding data, which appear to be quite noisy. Here are the links to data in Tableau tables. I'm looking for help with the analys...

Re: Situational change in attempt/ assist rate

Glad you are still working on it. Hope you get the further advice you seek. Would be curious to see the trends for J Kidd on all three stats. And Magic Johnson if you get back that far. Unfortunately, NBA.com data only goes as far back as 1996-97. So, no data for Magic. My data is finished compilin...
