9.7 Poisson Regression: The Model For Count Data

This video presented the poisson regression model equation that we use to model the outcome when it is a count.
These videos support a course I teach at The University of British Columbia (SPPH 500), which covers the use of regression models in Health Research. These videos were put together to use for remote teaching in response to COVID.

Thanks for posting this! This is helpful added info as I struggle through the MIT Micromasters in Data Science program.

Just discovered your content. You are a life savior! Thank you

Hello. I would like to ask a question, are there any test statistics to possibly use for underdispersed count data aside from generalized poisson model?

Hi, when you do the scatter plot between Ln(y) and X, which Xp are you considering? If I am not mistaken when you have more than one covariate you can´t graph the multiple linear regression

[@dariuszspiewak5624]

The graph for simplicity shows one variable X but you can have as many explanation variables as you want. If you have 2, say, you'll be fitting a plane to the points (x(p), y(p), ln(z(p)), p = 1,...,k. Same goes for any other number of dimensions. For 2 variables you still can sketch a 3D graph.
