Sunday data/statistics link roundup (3/24/2013)

  1. My Coursera Data Analysis class is done for now! All the lecture notes are on Github all the videos are on Youtube. They are tagged by week with tags "Week x".
  2. After ENAR the comments on how to have better stats conferences started flowing. Check out Frazee, Xie, and Broman. My favorite cherry picked ideas: conference app (frazee), giving the poster session more focus (frazee), free and announced wifi (broman), more social media (i loved following ENAR on twitter but wish there had been more tweeting) (xie), add some jokes to talks (xie).
  3. A related post is this one from Hilary M. on how a talk should entertain, not teach.
  4. This is a fascinating interview I found via AL Daily. My favorite lines? "You run into this attitude, that if ordinary people cannot set their Facebook privacy settings, then they deserve what is coming to them. There is a hacker superiority complex to this." I think this is certainly something we have a lot of in statistics as well.
  5. The CIA wants to collect all the dataz. Call me when cat videos become important for national security, ok guys?
  6. Given I just completed my class, the MOOC completion rates graph is pretty appropriate. I think my #'s are right in line with that other people report. I'm still trying to figure out how to know how many people "completed" the class.

    Is there a way to view the videos in order on youtube? (or somewhere else?)

    • R.K.

      You may refer to Jeff's notes on Github to get an idea of original order of videos.

    Providing free conference center wifi is ludicrously expensive. I mean, you might think $4 cups of bad drip coffee are overpriced, but that's nothing compared to the cost of free wifi. Especially for conferences in the US, you'd be better off paying for internet tethering on your phone than paying a conference fee that included free wifi -- unless you can get someone to sponsor it, as happened at the San Diego JSM in the exhibit hall.

    I took Data Analysis after having taken Computing for Data Analysis. I won't be taking the Mathematical Biostats Bootcamp, and I'm sorry about that; I promised my wife that I'd take a break from MOOC's. I had to. Our second child was born on the Friday before the first data analysis assignment was due. Anyway, I learned new tricks, and that matters more than the statement of accomplishment. This class gave me the impetus to set up knitr+LyX, on my work PC as well as on my own Mac. I had it on my list for about a year, and I should have just done it about as long ago. What a revelation! I'll never go back to writing code without ## @knitr or ``` markdown again, and I'll never again cut and paste code or results into documentation, either. So, thank you for doing this, and for giving me further evidence that MOOC's make the world a better place. Makes witnessing easier.

    Jeff, Could we please have the number of students who obtained certificates and certificates of distinction in the Data Analyis course? It appears that the 5500 number is the number of students who completed all the material, not the number who passed.

    Jeff, could you please let us know how many folks actually got a 'distinction' in your course? Thanks!

    I am one of the people who didn't complete the class. There were a few reasons for it.

    1) I didn't realize that Dr. Peng's Computing for Data Analysis was a pre/co-requisite. Trying to do both simultaneously was a bit difficult -- but strangely helpful and reinforcing. However, once his course timed out, I fell behind because I couldn't keep up with the nitty-gritty programming components of your course.

    2) For those of us with significant non-school commitments -- which in my case consists of an erratic job schedule, twin toddlers, and a mother with Alzheimer's -- sticking to a conventional college timeframe isn't possible without the same amount of family and financial support you'd get for going to a brick-and-mortar uni. I've had much better luck with Udacity's CS and Stats classes because of their flexibility.

    That said, I loved the actual class itself! Is there anyway you could also put it up at Udacity?

    I could view video lectures of first 2 weeks and attempt corresponding quizes before the course material was taken down from the site. I am eager to complete the remainder course, and curious to know tentative date of course relaunch?

    Though one can access videos on Youtube, quizzes/assignments, which are indispensable for gauging progress, are not consolidatedly archived. Or, have they been?

    Not to mention, lectures were delivered in lucid manner and I found them helpful for an upcoming assignment.
