Project One:

The method of analysis you will be asked to perform is linear regression.  The data set needs to have a dependent variable that is quantitative and at least two independent variables that are quantitative.  

Once you find a data set that you are interested in you need to get the approval of the instructor.  Some good web sites for finding data sets follow:

The analyses that you should run are:

  • descriptive statistics on each variable.
  • correlations between the dependent variable and each of the independent variables.
  • plot the dependent variable (y) versus each of the independent variables (x).
  • run a regression with all of your variables included in the model.
  • select the most significant variables for a final model.

Finally, you should write a report that includes a Title, an Introduction that describes where you got your data and what variables are involved, an Analysis section that describes and presents the relevant descriptive statistics, correlations, plots, and results of the regression analysis, and finally a Conclusions section summarizes you findings.

Assignment 9

  • Introduction to S-plus programming, graphics and gui.
  • vectors, matricies, data.frames, and lists
  • Sec 4.3 attach(geyser) help(geyser)
  • Sec 4.3 plot(geyser$waiting, geyser$duration)
  • Sec 5.4 type in pp.62-63 plots
  • Sec 5.5 type in p.66 sin
  • Sec 5.7 type in p.74 geyser plot

Assignment 10

  • Find a data set in the examples in Splus related to a topic of interest to you. 
  • Run the descriptive statistics and some plots.
  • Create a short report describing the data set you looked at and include the descriptive statistics and at least one plot.

Due 2/29/2000: Assignments 9 and 10.

Assignment 11

  • Run the CLT S-Plus program.  Change the mu and sigma values and print out the two pictures.
  • Run the Hypothesis Testing program can compare the estimated significance level for sampling from the normal to the exponential.
