sab-R-metrics: Intermediate Scatter Plots

January 25, 2011 | Millsy

First off, I'll say it's been a whirlwind of a past few days. Thanks to David Smith at the Revolutions Blog for his kind words about the sab-R-metrics series and link back this way. Add in Ed Kupfer's posts at the APBRmetrics board, Harry Pavlidis at THT, Dave Allen at ... [Read more...]

sab-R-metrics: Intermediate Boxplots and Histograms

January 20, 2011 | Millsy

Last week, I began talking about using the base graphics in R. Those graphics were pretty bland, and my hope for the next two posts is to introduce some interesting additions to the basic graphics that come from R: color, legends, lines, shapes, multiple graphs side-by-side, text, point types, and ...

sab-R-metrics: Basics of Vectors and Data Calling

January 6, 2011 | Millsy

Wednesday, I began a new series called "sab-R-metrics". My hope is that it reduces the frustration that goes along with learning a new programming language and enhances others' ability to perform their own analysis in baseball or other sports. However, these tutorials will hopefully allow you to use these skills ... [Read more...]

sab-R-metrics: Introduction to R

January 5, 2011 | Millsy

In a recent post, I briefly mentioned that I may turn a majority of the focus of this blog to teaching R commands for use with sabermetric analysis. Only a few days later, Ricky Zanker began a new column at The Hardball Times doing just that. But that's okay. Hopefully ... [Read more...]

IIATMS Guest Contribution

September 23, 2010 | Millsy

After my recent posts fiddling around with heat maps for pitch location, Jason at It's About the Money, Stupid contacted me to ask if I would contribute some location maps for Yankee pitchers. Obviously, I couldn't pass up the chance to contribute to ...

September 2, 2010 | Millsy

I tried using my own little palette with more traditional looking heatmap colors (red and pink are the densest, blue and green are less so, yellow in the middle, etc.). I also included the actual points, but would recommend it for more than a single g...

New Fantasy Ball Junkie Article

July 30, 2010 | Millsy

I have a new post up over at Fantasy Ball Junkie looking at the value of closers in H2H leagues from here on out. I simply simulated in the same way as the Stolen Bases and Home Runs articles from before. Saves are an interesting bunch, and it really...

Marking Your Graphics

June 2, 2010 | Millsy

Over at The Book Blog, Tango has a post about standardizing Pitch F/X graphs to be catcher/batter/umpire view. While I don't think this should necessarily be the case for all Pitch F/X graphics, it brings up another issue that I've had with some graph...

Trading for Speed in H2H Fantasy Leagues

June 1, 2010 | Millsy

As a followup to my last article at FBJ, I took a look at the distributions of weekly totals for Stolen Bases to gauge win expectancies in the SB category in H2H fantasy baseball formats. The study is again pretty simple, as I just subtract one hypoth...

Testing Out my Pitch F/X Data

May 25, 2010 | Millsy

I recently got all the Pitch F/X data downloaded from Gameday, and have been fiddling around. I certainly don't have the physics knowledge to really talk about the movement at this point, and I'm still acquainting myself with the data format and what e...

Fun with R: Clustering and MDS

May 5, 2010 | Millsy

I've seen K-means clustering, PCA, etc. done some over at Beyond the Boxscore and Baseball Analysts (and the now defunct Statspeak), but I thought I'd just check out some clustering on the young fantasy season using the traditional 5x5 categories with ...
