Wes McKinney and I are hosting our first ever Open Statistical Programming meetup tomorrow night after taking over for Drew Conway.  Please attend, have some pizza, enjoy the talk then come out for some beer.

This meetup is about EDA, Visualization and Collaboration on the Web and will be presented by Carlos Scheidegger from AT&T Labs.

This month’s pizza will be from Pizza Mercato in the Village.

Pi Day Celebrants

As mentioned earlier, yesterday was Pi Day so a bunch of statisticians and other such nerds celebrated at the new(ish) Artichoke Basille near the High Line.  We had three pies:  the signature Artichoke, the Margherita and the Anchovy, which was delicious but only some of us ate.  And of course we had our custom cake from Chrissie Cook.

The photos were taken by John.

Pi CakeHappy Pi Day everybody!  I’ll be out celebrating with the rest of the NYC Data Mafia eating pizza and devouring the above Pi Cake, custom baked by Chrissie Cook.

Today is also Albert Einstein’s birthday so there are plenty of reasons to have fun.

The cake below was my first ever Pi Cake in what is sure to become an annual tradition.

Update: Drew Conway does far more justice to our fair, irrational, transcendental number.

Update 2:  Engadget posted this awesome video of “What Pi Sounds Like.

Supreme Court Justice Antonin ScaliaDaily Intel caught wind of a California Lawyer interview with US Supreme Court Justice Antonin Scalia where he proclaims New York pizza “is infinitely better than Washington pizza, and infinitely better than Chicago pizza.”  I may be biased to New York pizza as well, but that is a debate I’ll save for another day.

It gets really interesting when he says, “You know these deep-dish pizzas—it’s not pizza. It’s very good, but … call it tomato pie or something.”  While an argument can certainly me made that deep-dish pizza is almost a casserole, I think the folks down in Trenton (where Scalia was born) have already claimed the name tomato pie, referring to a round pie with the sauce on top.

Hopefully Slice will chime in on this.

Last Wednesday I made a trip to Di Fara in Midwood, Brooklyn.  Since that place is well covered and lauded I won’t talk about the pizza, as amazing as it is. 

I gave Dom a copy of my thesis (pdf) on NYC pizza and he loved that his place was one of the few pizzerias mentioned by name (along with Lombardi’s and Otto Enoteca, two of my favorites) in the paper.  My friend captured these great photos and I’m extremely thankful to Dom for letting me in his kitchen. 

And to make the trip all the more surreal, Avenue J was lined with lulav and etrog vendors trying to clear out stock before Sukkot started.  The juxtaposition of Di Fara and the surrounding Orthodox neighborhood was striking and really shows the beauty of New York City.

After years of waiting a new Artichoke Basilles our dreams have been answered.  The new spot, which hasn’t even been updated on the website yet, is at 17th and 10th opened this weekend.  Unlike the original location this one has seats and wait service and only sells pies, albeit smaller than the originals.  There is a side shop where they sell slices, but I didn’t venture in there.

The pie, seen below in the blurry iPhone shot, is just a smaller version of the pies at the original shop and were just as tasty.  One pie was too much food for a friend and me, so figure one pie ($17) for 2.5 to 3 people.

Additionally, they have a larger selection of pies and non-pizza food, such as salad and the sorts.  They don’t have beer or liquor yet, but should soon.

Last week Slice ran a post about a tomato taste test they conducted with Scott Wiener (of Scott’s NYC Pizza Tours), Brooks Jones, Jason Feirman, Nick Sherman and Roberto Caporuscio from Keste.  While the methods used may not be rigorous enough for definitive results, I took the summary data that was in the post and performed some simple analyses.

The first thing to note is that there are only 16 data points, so multiple regression is not an option.  We can all thank the Curse of Dimensionality for that.  So I stuck to simpler methods and visualizations.  If I can get the raw data from Slice, I can get a little more advanced.

For the sake of simplicity I removed the tomatoes from Eataly because their price was such an outlier that it made visualizing the data difficult.  As usual, most of the graphics were made using ggplot2 by Hadley Wickham.  The coefficient plots were made using a little function I wrote.  Here is the code.  Any suggestions for improvement are greatly appreciated, especially if you can help with increasing the left hand margin of the plot.  And as always, all the work was done in R.

The most obvious relationship we want to test is Overall Quality vs. Price.  As can be seen from the scatterplot below with a fitted loess curve, there is not a linear relationship between price and quality.

More after the break. Continue reading

The other day I found myself walking down 7th Avenue South, as is usual, and I decided to pop into Blecker Street Pizza.  I haven’t been there in years because of all the other great pizza in the neighborhood like John’s, Keste, Number 28 (which is claimed best by Citysearch), Risotteria (so I’ve heard) and Joe’s.

I remember not being a blown away by the place and I reaffirmed that this time.  It’s not awful but it certainly isn’t the Best Pizza in New York as the Food Network seems to think.  With all the good options around the area I think it will be a while before I pop back inside.

This makes me doubt everything the Food Network says.  I’ll be sticking to Travel Channel’s Man v Food starring Adam Richman who regularly shows his affinity for Lombardi’s with his t-shirts (as seen below) and loves L&B Spumoni Gardens.
