Introduction to Poisson Regression

13 May 2024, 9:30 am–5:00 pm

This course introduces regression methods that are appropriate to analyse count or rate data. Poisson regression is used to determine associations between a count/rate outcome and a number of predictor variables. More flexible extensions of the poisson regression, quasi poisson and negative binomial regressions, are also introduced and explained.

NOTE: This course will be delivered in hybrid mode, i.e. the in-person lecture will be transmitted live on zoom. The face-to-face part of the hybrid courses will go ahead conditional on at least 5 participants registering for this mode of delivery. Few classes may be delivered exclusively online, so please check under the Future dates tab for clarification. The online part of the class will be supported by its own dedicated teaching staff (along with the lead lecturer), therefore participants can expect the same level of group and individual support as the face-to-face class. You will be able to choose your preferred mode of attendance (face-to-face or online) during registration. 


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. 

This course explores how poisson regression models are formulated, interpreted and checked using worked examples. The course also details how poisson regression can be extended when the strict assumptions are not met (introducing quasi poisson and negative binomial models). 

Please note that this course does not involve hands-on use of a statistical package, results will be given in the notes and care has been taken to ensure they are comprehensible regardless of which statistical package delegates are used to. The course assumes a basic understanding of statistical concepts such as p-values and confidence intervals.

It's great to be taught by someone who not only enjoys the content but also enjoys sharing her knowledge. And in a way that is comprehensible, which is a skill, really! Many thanks.

Sophie was very clear and enthusiastic!

Very good presentation, clear explanation. Excellent course materials. Good answering of questions. Helpful to have examples of papers and questions to work through to test knowledge. 

Excellent, well done!

Generally an excellent course and very well taught.
