Material for wk. 4, linear regression. Update 4/26

  1. NEW!  Playstation  #SIE-PSN teams – I am setting up a page for information about this project. THE DEADLINE IS NOW – you must be either IN or OUT so we can move forward. On the + side, Sony is very serious about hiring, and the experience you will get will be immediately relevant to many potential employers. On the – side, you will need to be a self-starter, seek out documentation and information yourself, and generally have a “hands-on” attitude. For example, in order to understand the data coming from the Sony SIE website, you will need to actually visit and examine the site.
  2. NEW!  Lecture notes from Monday 4/23 and 4/25 Updated to Wednesday. BDA18 regression 2018B.key
  3. For the EPA homework, I found a Word document containing the R code. It may be easier to work with BDA16S BohnDA-gram data editing in R Other than the format, it should be almost identical to the one posted with the homework.
  4. The best books and sites about R and data mining. For each project, there are some specialty books and web sites that can save you hours or even days of effort.  It is organized into:
    • Reference books
    • Cheat sheets
    • Resources for learning R
    • Books on special topics.
  5. The minute you start working with R directly, run to this page and download a few resources. Especially get at least 1 cheat sheet. I handed one out in class – now get the e-version.
  6. Answers to some short homework questions from last week – I will post them soon.
  7. NEW! Answers to questions that were on the yellow post-its. DONE
  8. Study guides for ROC curves and other topics about classification models (week 3). I have put them on a new page of supplemental notes. Lecture note supplements
  9. We got a fan note from the author of our Rattle book:
    Hi Roger,

    Just saw your blog post on installing Rattle on mac OS X. Thank you so much for that.
    I’ve added a pointer on my rattle install page (https://rattle.togaware.com/rattle-install-mac.html  … which needs a refresh one day :-).
    You are correct, I don’t have any ready access to a Mac and spend most of my time on Linux.
    It is great that you shared your experience – I know many others will find this useful and no doubt will be appreciative as well.
    All the best.

    Regards,
    Graham
