Pizza Talk

Posted on by | Leave a reply

This Thursday, April 8th, I’ll be giving two brief talks (5 to 10 minutes) about statistical methods at the New York R User Meetup.  The first will be applying multilevel models to World Health Organization data to study noncommunicable diseases.  The second, and probably more fun, will be a presentation of my pizza paper (pdf) that was featured on Slice.

Just Filled Out the Census

Posted on by | Leave a reply

I just filled out my Census form and I have to say it was fairly painless and simple.  The short form (pdf) really only asks about age, ethnicity and other residences.  If anyone has a long form (now called the American Community Survey), please let me know your experiences filling that out.

The question concerning residence can be a bit tricky these days with so many people having multiple residences, children who live on their own but visit home frequently and couples who live togetherbut also maintain separate residences.

Overestimating Taxes

Drew Conway has a piece on his Zero Intelligence Agents blog about how well informed Tea Party protesters are about tax policy.  His analysis is pretty technical and he even offers up the R code he used to analyze the data and build the graphs which were made with a package called ggplot2 by Hadley Wickham at Rice University.

More after the break. Continue reading →

Inflatable Census

Posted on by | Leave a reply

Being a stats junkie I’m probably more excited about filling out my Census forms than most people.  That said, a lot of my friends have expressed glee at receiving their Census forms.  Perhaps that says something about social group.

So you can imagine my delight when I came across this giant, inflatable Census form in Union Square last Saturday night.

I’m not sure about other markets, but there has been a huge advertising blitz for the Census in New York including the commercials featuring actors from the “Best in Show” and “A Mighty Wind” movies.

One more closeup of the moon-bounce inspired Census form after the break.

I don’t mean to shamelessly self-promote here, but I wanted to note that the Slice story on my pizza paper (pdf) has also been picked up by NBC New York’s food blog, Feast, and by Revolution Computing’s blog.  For people who don’t know, Revolution Computing optimizes R, the language used by a large number of statisticians for computations.

Midtown Pizza

The Slice article got picked up by MidtownLunch.

A lot of people have been asking for my favorite pizza places.  The answer depends on what type of pizza I’m looking for, but Maffei’s grandma slice and and Keste are two places that pop into my head a lot.

Someone at the ML forum asked about New York Pizza Suprema, and yes, I love their upside down slice.

Statistics of Pizza

Slice has a nice writeup of a paper I wrote performing a statistical analysis of New York City.  The article is nicely written and distills the analysis to the parts people will care about.  See here for the corresponding PowerPoint presentation.

Math and Sciences

Posted on by | Leave a reply

I’ve decided to use this space to talk about math, statistics and science applied to everyday things in new or interesting ways.

This will not be an overly technical blog, though I will make the hard science behind the posts available when possible.  The point is to make science accessible and fun and see how it affects our everyday lives.

I hope you enjoy reading my blog.  I will strive to make it as good and enjoyable as can be.
