Homework assignments, after the first two, require use of the R statistical computing package. The original Course Notes used the Minitab package, but R is now much more widely available, and it is free. The material linked below includes an R Software Introduction for Stat 571 to help you get started. In addition, we rewritten the Appendix information from the Course Notes using R.
Remember, computing parts of homework should clearly show what you did and how. Be concise; condense computing session to highlight findings. Organize your analysis and interpret your results as instructed in the assignments.
Each appendix has a separate file of R code for the examples of that appendix. You can either open that R code by clicking below, or use the R source command as shown below to see the results on your own system. Here is one way to source the Appendix 2 commands from inside R, if you are on the Internet:
par( ask = TRUE ) source( "http://www.stat.wisc.edu/~yandell/st571/R/append2.R", echo = TRUE )The par command sets ask=TRUE to force a pause between plots. (Hit the RETURN key to show the next plot.) The source command executes the commands in the R code file "append2.R", setting echo=TRUE to show you exactly what is done.
