 Tuesdays and Thursdays, 1:00-2:55pm
Location: Purvis room 25
Office hours: 
Tuesdays 9:30-11:00pm in Purvis room 48 or by appointment

Erica E. M. Moodie and Olli Saarela

TA: TBA
TA office hour: TBA
Prerequisite: Basic understanding of differentiable and integral calculus.
Enrollment in the Epidemiology program at McGill University.
 
Objectives: The aim of this course is to provide students with basic principles of statistical inference applicable to clinical and epidemiologic  so that they can: (i) understand how statistical methods are used by others, (ii) apply statistical methods in their own research, and (iii) use the methods learned in this course as a foundation for more advanced biostatistics courses.

Note: These are excellent books. If you have a friend in the class with whom to share a book, you may want to consider buying one copy of this and one of Baldi & Moore.


Equipment: Hand calculators (with square root, log, and exponential function) are required.  The R software package will be introduced and used for in-class illustrations. R is available under GPL (free) at http://lib.stat.cmu.edu/R/CRAN.
Evaluation: Assignments                                                                                             20%
Mid-term exam                                                                                       30%
Project                                                                                                        10%
Final exam                                                                                                40%


The final grade will consist of a letter grade. This will be determined by taking the maximum of:

                   (Homework/Project 30% + Midterm Exam 30% + Final exam 40%)

and                                  (Homework/Project 30% + Final Exam 70%).

 
The midterm will be held in class date October TBA (closed book, but you may bring one 8x11 sheet of notes).
The project is due TBA.
The final will be held TBA (closed book, formula sheet provided).


No make-up work will be allowed for assignments unless a valid & demonstrable reason is presented
within one week of the original due date.
