Although it’s probably the technique most employed by statisticians, regression or at least multiple linear or multiple logistic regression, is often the concept that is most feared or misunderstood by students and newbie researchers. If someone you know is in the latter categories, and they would like a fun and straightforward introduction to regression that literally uses pictures (cartoons), announce that The Manga Guide to Regression book has now been published, around May 2016, by the friendly folks at NoStarchPress http://www.nostarch.com/regression
and available on http://www.oreilly.com http://www.amazon.com http://www.bookdepository.com http://www.dymocks.com.au etc
Authored by Shin Takahashi (Manga Guide to Statistics, 2008), the new book uses Manga http://en.wikipedia.org/wiki/Manga (think Osamu Tezuka’s Jungle Emperor: made into the 1965 Japanese anime TV series of the same name and the 1966 US overdub ‘Kimba the White Lion’ http://en.wikipedia.org/wiki/Jungle_Emperor, as well as ‘Atomu’ / Astro Boy’ .
Okay, Kimba himself is not actually included in the Manga Regression book, but there’s both linear and logistic regression, demonstrated using Microsoft Excel (just a slight gritting of teeth, go for Excel 2010/2013/2016 or higher, but at least it might allow getting ‘down and dirty with data’.
