Comment on hello, world of statistical graphics in IPython notebook by Abraham Flaxman

Maybe it is an IPython version issue. I’m using a nearly up-to-date version of the version here: https://github.com/ipython/ipython

If you don’t have %%javascript magic, you can try wrapping the cell contents with Javascript(""" … """), which also works for me.

Having trouble with the javascript magics on 0.13.2.

“ERROR: Cell magic function `%%javascript` not found.”

any ideas? I’m really interested in this topic and would like to see the side-by-side.

I don’t know of translation book, but it seems like now is the time for someone to write one. What do you want translated?

This generated quite a list of follow-up readings:

Matching:

A cool application:

American Academy of Pediatrics: Janet Elise Rosenbaum, Patient Teenagers? A Comparison of the Sexual Behavior of Virginity Pledgers and Matched Nonpledgers, Pediatrics, Vol. 123 No. 1 Jan 2009.

What’s Known on This Subject

Two studies have found, by using regression, that virginity pledges delay sex, but regression cannot correct for large preexisting differences between pledgers and nonpledgers.

What This Study Adds

We used a more robust method than regression to compare virginity pledgers with similar nonpledgers and found virtually no difference in sexual behavior or STDs and much less use of condoms.

A validation environment that calls the method into questions
