Poisson Regression: an Introduction

  • 5 hours
  • 1 day

Overview

This one-day course will introduce you to regression methods for analysing count or rate data.

You'll learn about:

  • poisson regression - used to determine associations between a count/rate outcome and a number of predictor variables
  • quasi poisson and negative binomial regressions - more flexible extensions of the poisson regression

You should have a basic understanding of statistical concepts such as p-values and confidence intervals before attending this course.

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

When dealing with a count or rate outcome variable, basic linear regression is inappropriate as it will lead to invalid predictions.

Poisson regression is an extension of the ideas used in linear regression that allows counts or rates to be validly modelled against chosen predictor variables.

You'll explore how poisson regression models are formulated, interpreted and checked using worked examples.

You'll learn how poisson regression can be extended when the strict assumptions are not met, by using quasi poisson and negative binomial models.

This course doesn't involve hands-on use of a statistical package. You'll be given results in the notes, which should be comprehensible regardless of which statistical package you are used to.

Learning outcomes

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

  • understand what poisson regression is and when to use it
  • formulate and interpret poisson regression models for counts and/or rates
  • know the diagnostic statistics and assumptions that must be checked to ensure poisson models are valid
  • know when to consider quasipoisson and negative binomial models and how to interpret them

Cost and concessions

The fees are as follows:

  • External delegates (non UCL) - £150
  • UCL staff, students, alumni - £75*
  • ICH / GOSH staff and students - free    

* valid UCL email address and/or UCL alumni number required upon registration

Prices include printed course materials, refreshments (and lunch for non-ICH  participants).

Certificates

You can request a certificate of attendance for this course once you've completed it. Please send your request to ich.statscou@ucl.ac.uk

Include the following in your email:

  • the name of the completed course for which you'd like a certificate
  • how you'd like your name presented on the certificate (if the name/format differs from the details you gave during registration)

Cancellations

We accept cancellations up to five working days before the start of the course with a full refund, though we'd appreciate as much notice as possible to re-allocate the place. Places cancelled or changed after this point won't be eligible for a refund. Please send all cancellation requests directly to the course administrator
