Introduction: There was some confusion on my last try , so let me explain one more time . . . The flights I where Hipmunk failed (see here for background) were not obscure itineraries. One of them was a nonstop from New York to Cincinnati; another was from NY to Durham, North Carolina; and yet another was a trip to Midway in Chicago. In that last case, Hipmunk showed no nonstops at all—which will come as a surprise to the passengers on the Southwest Airlines flight I was on a couple days ago! In these cases, Hipmunk didn’t even do the courtesy of flashing a message telling me to try elsewhere. I don’t understand. How hard would it be for the program to automatically do a Kayak search and find all the flights? Hipmunk’s graphics are great, though.

2 0.48204014 2238 andrew gelman stats-2014-03-09-Hipmunk worked

Introduction: In the past I’ve categorized Hipmunk as a really cool flight-finder that doesn’t actually work , as worse than Expedia , and as graphics without content . So, I thought it would be only fair to tell you that I bought a flight the other day using Hipmunk and it gave me the same flight as Expedia but at a lower cost (by linking to something called CheapOair, which I hope is legit). So score one for Hipmunk.

3 0.47010782 497 andrew gelman stats-2011-01-02-Hipmunk update

Introduction: Florence from customer support at Hipmunk writes: Hipmunk now includes American Airlines in our search results. Please note that users will be taken directly to AA.com to complete the booking/transaction. . . . we are steadily increasing the number of flights that we offer on Hipmunk. As you may recall, Hipmunk is a really cool flight-finder that didn’t actually work (as of 16 Sept 2010). At the time, I was a bit annoyed at the NYT columnist who plugged Hipmunk without actually telling his readers that the site didn’t actually do the job. (I discovered the problem myself because I couldn’t believe that my flight options to Raleigh-Durham were really so meager, so I checked on Expedia and found a good flight.) I do think Hipmunk’s graphics are beautiful, though, so I’m rooting for them to catch up. P.S. Apparently they include Amtrak Northeast Corridor trains, so I’ll give them a try, next time I travel. The regular Amtrak website is about as horrible as you’d expect.

Introduction: Brendan pointed me to this news article by David Pogue promoting a website called Hipmunk , a sleek competitor to Travelocity, Expedia, Kayak, and the like. Coincidentally, I had to a buy a flight right now so I followed the link and found that, indeed, Hipmunk is about a zillion times easier to use and more impressive than Expedia or even Kayak. It’s awesome. The others aren’t even close. The display was so clean and effective, I felt like ordering a few flights just for fun. That’s the good news. Now the bad news. I wasn’t just playing around with the site. There was actually a flight I wanted to buy–an itinerary I’d looked into yesterday but hadn’t saved or booked. I effortlessly set up the request in Hipmunk, scanned its impressive graphical display, and . . . couldn’t find the flight I wanted! Oh no! The last ticket must’ve been sold! Just to check, though, I want on good old ugly Expedia. And my flight was right there! So I bought it. So, just a quick memo

Introduction: I love a good GUI but not if it doesn’t give me the information I need. I again tried Hipmunk and it again failed (this time for a trip to Baltimore where it gave only a useless subset of the available Amtrak trains). I don’t know anything about the internet biz. What I’m guessing is that they set up this cool website that is pretty much functional, with the goal of selling it for a few million dollars to Travelocity or Expedia or Kayak. What I’m wondering is, why haven’t they made the deal already? Hipmunk’s GUI is great. The site is useless because it’s missing so many flights, but if you put it in an actual travel site such as Expedia, it would be great. It’s enough to make me want to hit someone with an i-phone . . .

Introduction: Awhile ago I was cleaning out the closet and found some old unread magazines. Good stuff. As we’ve discussed before , lots of things are better read a few years late. Today I was reading the 18 Nov 2004 issue of the London Review of Books, which contained (among other things) the following: - A review by Jenny Diski of a biography of Stanley Milgram. Diski appears to want to debunk: Milgram was a whiz at devising sexy experiments, but barely interested in any theoretical basis for them. They all have the same instant attractiveness of style, and then an underlying emptiness. Huh? Michael Jordan couldn’t hit the curveball and he was reportedly an easy mark for golf hustlers but that doesn’t diminish his greatness on the basketball court.

Introduction: Stan is written in C++ and can be run from the command line and from R. We’d like for Python users to be able to run Stan as well. If anyone is interested in doing this, please let us know and we’d be happy to work with you on it. Stan, like Python, is completely free and open-source. P.S. Because Stan is open-source, it of course would also be possible for people to translate Stan into Python, or to take whatever features they like from Stan and incorporate them into a Python package. That’s fine too. But we think it would make sense in addition for users to be able to run Stan directly from Python, in the same way that it can be run from R.
