### Logistic Regression - Adv

Advanced Logistic Regression

taught by Joe Hilbe

Aim of Course:

After taking this online course, "Advanced Logistic Regression" participants will be able to specify, implement and interpret the output of a variety of advanced logistic regression models. This course moves beyond the topics covered in "Logistic Regression" and covers a number of situations that call for logistic-based modeling, including a variety of ordered-categorical response (both proportional and non-proportional) models, multinomial models, panel models with fixed and random effects, GEE and quasi-least-squares models, multi-level models, survey logistic models, discriminant logistic models, skewed and penalized logistic regression, median unbiased estimation, Monte Carlo sampling, and exact logistic regression.

Course Program:

WEEK 1 - Proportional Odds Models

- Overview of binary logistic regression
- Overview of binomial logistic regression
- Proportional odds models

WEEK 2 - Multinomial Response Model

- Ordered non-proportional models
- Multinomial logistic regression
- Multinomial probit regression
- Alternative categorical response models
- Marginal effects and discrete change

WEEK 3 - Panel and Mixed Models

- Panel models
- GEE/Quasi-least squares models
- Fixed- and random-effects models
- Multi-level models

WEEK 4 - Penalized and Exact Models

- Survey models
- Exact logistic regression
- Penalized logistic regression
- Monte Carlo sampling methods
- Median unbiased estimation

Homework:

The homework in this course consists of short answer questions to test concepts, guided exercises in writing code and guided data analysis problems using software.

In addition to assigned readings, this course also has example software codes, supplemental readings available online, and an end of course data modeling project.

Who Should Take This Course:

Researchers in medicine, other life sciences, business, social science, environmental science, engineering and other fields who need to predict or model 1/0 or "yes-no" binary type responses as well as models having categorical and proportional responses. Those who deal with classifying data into risk groups as well as those who handle longitudinal and clustered data will find the course valuable.

Level:

intermediate/advanced

Though it is not required for practical applications of material in this course, some familiarity with calculus (see Statistics.com's brief Calculus Review course) is helpful for a complete understanding of model development.

Organization of the Course:

This course takes place online at the Institute for 4 weeks. During each course week, you participate at times of your own choosing - there are no set times when you must be online. Course participants will be given access to a private discussion board. In class discussions led by the instructor, you can post questions, seek clarification, and interact with your fellow students and the instructor.

At the beginning of each week, you receive the relevant material, in addition to answers to exercises from the previous session. During the week, you are expected to go over the course materials, work through exercises, and submit answers. Discussion among participants is encouraged. The instructor will provide answers and comments, and at the end of the week, you will receive individual feedback on your homework answers.

Time Requirement:

About 15 hours per week, at times of your choosing.

Credit:

Students come to the Institute for a variety of reasons. As you begin the course, you will be asked to specify your category:

- You may be interested only in learning the material presented, and not be concerned with grades or a record of completion.
- You may be enrolled in PASS (Programs in Analytics and Statistical Studies) that requires demonstration of proficiency in the subject, in which case your work will be assessed for a grade.
- You may require a "Record of Course Completion," along with professional development credit in the form of Continuing Education Units (CEU's). For those successfully completing the course, CEU's and a record of course completion will be issued by The Institute, upon request.

Course Text:

The course text is *A Practical Guide to ogistic Regression* by Joseph Hilbe.

PLEASE ORDER YOUR COPY IN TIME FOR THE COURSE STARTING DATE.

Software:

No single software package is capable of doing all the models covered in this course, though Stata comes closest and is used for illustrations and the instructor is most familiar with Stata. Click Here for information on obtaining a free (or nominal cost) copy of various software packages for use during the course. R code is also supplied for many illustrations. The homework can effectively be done in Stata, R or SAS.

Note: If you are planning to use R in this course and are not already familiar with it, please consider taking one of our courses where R is introduced from the ground up: "Introduction to R: Data Handling," "Introduction to R: Statistical Analysis," or "Introduction to Modeling." R has a learning curve that is steeper than that of most commercial statistical software.
