  Probability

  • Home work:
    • Should there be a lack of attendance accompanied by an increasing number of homework assignments showing up in the grader's box during class time, assignments will no longer be posted.  Come to class to find out what is due and when.
      • Homework 1
    • Scores
  • Handouts:
  • R/S-Plus Code:
  • Data Files:
  • Java Applets:
    • Pass the Oinkers:  A fun way to get a feel for probabilities and expected values.  Play the game here or download everything you need to play it on your Java enabled machine.
  • Utilities:
    • R is a freeware "statistical package".  It has been compiled to run under Windows, Mac OSX, and Linux -- other versions are probably around.  R is actually a vectorized, object oriented programming language with a large library of statistical functions already written for it.  It is used in a number of graduate programs and companies.  R is known for its flexibility and its presentation quality graphics. Not- guaranteed-to-be-most-recent versions for Windows and Mac OSX as well as the Windows installation notes are available locally by clicking on the appropriate version.  If possible, you should download the executables directly from the CRAN.
    • The very much not free version of R is S-Plus which has a somewhat nicer front end and about a $2000 street price.  Academics get a discount, and students can get a free version.  For those who care, S came first (Bell Labs), then S-Plus showed up (work at UW and then Insightful), and then people came back with R. 
    • NCSS (Number Cruncher Statistical Software) is not free.  However, there is a trial version that works for 14 days on 100 or fewer observations.  NCSS is available on campus.
    • SAS (Statistical Analysis System) is used by many Fortune 500 companies.  It contains both analytical and data management tools.  However, its graphics are weak.  It is also very expensive -- particularly to small liberal arts colleges.  A working knowledge of this package can definitely get you a job.
