Trump Lies

The New York Times recently cataloged all of President Trump's lies since he took office. Here is breakdown of the topics of those lies over time.

200 Songs of Springsteen

Bruce Springsteen is awesome. His music is personally very important to me. So I wanted to make a viz to celebrate his amazing career. This analysis looks at patterns in his music by song including song loudness, valence, lyric sentiment, energy, acoustic levels, and popularity. You can also find similar songs to the ones you like at the bottom. Hope you enjoy.

Predicting QB Success in the NFL

Last year I wrote and submitted a paper for the MIT Sloan Sports Analytics Conference. While my abstract was accepted my paper was not. The title of my paper was Reducing Risk in the NFL Draft: Using Machine Learning Algorithms to Predict Success in the NFL. You can read the full paper here. 

In it I describe a decision tree model that predicts a college QBs success in the NFL. To train the model I used over 40 variables including college stats, school competitiveness, combine performance, and text mining of pro scouting reports. Ultimately, the final model used 4 variables: college win %, body mass index (BMI), college games started per season, and age. The final model was 88% accurate in predicting whether a college player would be a success or a bust in the NFL. This model can be used to predict whether the top prospects in this year's draft will be successful in the NFL.

Below is an interactive version of that final QB model.

NFL Combine & Triangle/Ternary Plot

Triangle/Ternary plots are a good way of displaying the relative positioning of points across three variables. This can be used to cluster and classify points based on these three variables. After the break I have outlined a way of creating an interactive version of a triangle/ternary plot in Tableau.

Here is an example of a triangle/ternary plot on the performance of collegiate players at the 2017 NFL combine across three variables: size (BMI), speed (40 time) and strength (bench press).

Spark Bar Chart

A spark bar chart, at least that is what I am calling it for now, combines a sparkline and a bar chart into one chart. The length of the bar is a value corresponding to the end of the sparkline which represents the last period or current value. In the example below the bar represents sales in December 2015 and the sparkline is sales by month for the last 4 years.
