# MA44200 Multivariate Analysis I (Honors)

Purdue University Spring 2012

## Friday, April 27, 2012

### Final Project

Due: Fri, May 4, 12:20pm

[Final Project]

Submission: From around noon on Mon, Apr 30, an envelope will be affixed at the door of my office MATH 610. Place the completed project into the envelope before 12:20pm on Fri, May 4.

### Final Score

Two schemes for calculating your final score will be used: with or without final project.

Scheme I = (3/10)ME1 + (3/10)ME2 + (1/5)FP + (1/5)HW
Scheme II = (3/8)ME1 + (3/8)ME2 + (1/4)HW

where FP, MEi, HW are the scores (in %) for Final Project, Midterm Exam i, Homework

You will have to contact me (by email) by Fri, Apr 27 (last day of classes) to tell whether you will be completing the Final Project (Scheme I will be used) or not (Scheme II will be used). If you do not contact me by then, your score will be calculated according to Scheme I.
