Logistic Regression: an Introduction

  • 9:30am to 1pm
  • 2 days

Overview

This short course focuses on understanding the principles of logistic regression using the notions of odds, odds ratios and transformations.

It includes discussion of how good the given model is, and ways of improving it.

This course takes place online, over two mornings (9:30am to 1pm). There is also a self-paced, online version of this course that you can register for and start at any time. 

Due to the coronavirus outbreak, this course will be run online through a live video feed.

This course is delivered by UCL's Centre for Applied Statistics Courses (CASC), part of the UCL Great Ormond Street Institute of Child Health (ICH).

Course content

Binary (proportion/percentage) outcomes are common in medical and scientific research. However, such outcomes can't be validly analysed using basic linear regression analysis.

It's important to understand how to analyse binary outcomes appropriately to ensure you can draw useful and valid conclusions from the data.

The course covers the following key topics:

  • Odds ratios as a means of comparing binary outcomes between two groups
  • How logistic regression allows for other factors within this comparison
  • The basics of logistic regression
  • Model selection and goodness-of-fit with applied examples
  • Interpretation of SPSS output
  • Discussion of extension to the analysis of ordinal outcomes

Learning outcomes

By the end of the course you should be able to:

  • understand when it is relevant to choose logistic regression
  • understand the use of odds, odds ratios and transformations in logistic regression
  • correctly interpret the results of logistic regression
  • choose the best logistic model that describes the relationship under question
  • understand how logistic regression can be extended for nominal and ordinal outcomes
