DSC 410/510 - Multivariate Statistical Methods

Assignment 7 (deadline: 4pm on Monday, October 25)

Practical matters

Jobs example (continued):

• Work through "jobspw3.sas" (available from the handouts page of the class web-site) which provides SAS code and instructions for running hierarchical and non-hierarchical cluster analyses on the jobs example part-worths (available in the "jobspw3.xls" spreadsheet available from the data page). In particular:
  • run Ward's minimum variance cluster analysis, including producing a dendogram
  • run a 2-cluster non-hierarchical analysis using hierarchical cluster means as initial seeds
  • profile the 2-cluster non-hierarchical solution and assess significant differences
  • profile the solution on additional variables not used in the clustering procedure
  • produce a profile plot in Excel which includes the average partworths from the conjoint exercise for each cluster
• Send an e-mail to ipardoe at lcbmail.uoregon.edu with a brief description of how you would characterize the main differences between the two clusters (both in terms of the part-worths from the conjoint analysis, as well as the demographic information on age, work experience, salary expectation, and student status).
