COURSE DESCRIPTION: This course offers students advanced instruction in statistical models that cover
useful quantitative tools in public health research. The course focuses on statistical techniques and data
analysis that utilize general linear regression models for continuous, categorical, or discrete outcomes
commonly seen in health and policy studies. Examples are drawn from broad areas of public health and
policy research. In this course students will gain knowledge and understanding of statistical concepts of
generalized linear models and the implementation and application of the techniques.
COURSE OBJECTIVES:
By the end of the course, students will be able to:
1. Learn about the different characteristics of continuous, categorical and discrete outcomes, and their
inherent challenges to data analysis.
2. Be introduced to and master the use of a wide range of statistical models, including linear, logistic,
and Poisson regression models.
3. Build skills in applying appropriate regression models to analyze data and interpret results using
statistical software.
4. Develop writing skills for quantitative research on public health and policy research.
5. Gain knowledge of statistical theories, specifically likelihood-based inferences, which justify
statistical practices.
PRE-REQUISITES: None for PhD students. Masters students must have completed 20 credits, have a GPA
of 3.5 or higher, and receive permission of the instructor.

COURSE REQUIREMENTS AND EXPECTATIONS:
Course requirements consist of required readings, two problem sets and two projects. Most of the
material of the course is covered in formal lectures, and remaining is assigned as optional readings.
Students should have access to the SAS program and are encouraged to frequently practice SAS
procedures learned in the class. All problem sets must be submitted at the beginning of class on the due
day, and all projects must be submitted by email before 5pm on the due day. No late submission will be
accepted without instructor’s permission before it is due.

STATEMENT OF ACADEMIC INTEGRITY:
The NYU Global Institute of Public Health values both open inquiry and academic integrity. Students in
the program are expected to follow standards of excellence set forth by New York University. Such
standards include respect, honesty and responsibility. The GIPH does not tolerate violations to academic
integrity including:
 Plagiarism
 Cheating on an exam
 Submitting your own work toward requirements in more than one course without prior
approval from the instructor
 Collaborating with other students for work expected to be completed individually
 Giving your work to another student to submit as his/her own
 Purchasing or using papers or work online or from a commercial firm and presenting it as your
own work
Students are expected to familiarize themselves with the GIPH and University’s policy on academic
integrity as they will be expected to adhere to such policies at all times – as a student and an alumni of
New York University.
Plagiarism
Plagiarism, whether intended or not, is not tolerated in the GIPH. Plagiarism involves presenting ideas
and/or words without acknowledging the source and includes any of the following acts:
 Using a phrase, sentence, or passage from another writer's work without using quotation marks
 Paraphrasing a passage from another writer's work without attribution
 Presenting facts, ideas, or written text gathered or downloaded from the Internet as your own
 Submitting another student's work with your name on it
 Submitting your own work toward requirements in more than one course without prior
approval from the instructor
 Purchasing a paper or "research" from a term paper mill.
Students in the GIPH and GIPH courses are responsible for understanding what constitutes plagiarism.
Students are encouraged to discuss specific questions with faculty instructors and to utilize the many
resources available at New York University.
Disciplinary Sanctions
When a professor suspects cheating, plagiarism, and/or other forms of academic dishonesty,
appropriate disciplinary action is as follows:
3

The Professor will meet with the student to discuss, and present evidence for the particular
violation, giving the student opportunity to refute or deny the charge(s).
 If the Professor confirms that violation(s), he/she, in consultation with the Program Director may
take any of the following actions:
o Allow the student to redo the assignment
o Lower the grade for the work in question
o Assign a grade of F for the work in question
o Assign a grade of F for the course
o Recommend dismissal
Once an action(s) is taken, the Professor will inform the Program Director, and inform the student in
writing, instructing the student to schedule an appointment with theAssociate Dean for Academic
Affairs, as a final step. The student has the right to appeal the action taken in accordance with the GIPH
Student Complaint Procedure.
STUDENTS WITH DISABILITIES:
Students with disabilities should contact the Moses Center for Students with Disabilities regarding the
resources available to them, and to determine what classroom accommodations should be made
