9.12 Poisson Regression: Why are model coefficients the log rate ratio?
This video goes over an explanation of why the model coefficients are log rate ratios. Or, why when we exponentiate the model coefficients do we get rate ratios?
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.

9.9 Poisson Regression: The Model For Rate Data (what is an offset?)
Просмотров 13 тыс.3 года назад
This video discusses the poisson regression model equation when we are modelling rate data. The model differs slightly from the model used when the outcome is a count. The main difference is that we must include an "offset" in the model. This video explains the concept of an offset.... the offset is just a fancy word for the denominator in the rate....in the model, we must include this as a sep...

9.6 Intro To Data Used In Poisson Regression R Videos
Просмотров 4,2 тыс.3 года назад
In this video I introduce the 2 datasets we use to examine poisson regression. one data set is at the individual level and we model counts. The other data set is aggregated and we model rates (which requires use of an offset).

9.5 Poisson Regression: Counts vs Rates, Individual vs Aggregated Data
Просмотров 7 тыс.3 года назад
This video discusses the types of data we may model using poisson regression. Specifically, I talk about when we can model the "counts" vs when we must model a "rate". I also talk about when we may model data recorded on an "individual level" versus when we must "aggregate" the data.

9.3 Poisson Regression Connection To Poisson Distribution and Odds Ratios
Просмотров 6 тыс.3 года назад
This video makes connections to material typically covered in intro statistics courses. First, I review the poisson process which gives rise to the poisson probability distribution. I then demonstrate how we can use Poisson regression to estimate the rate at which events are occurring (which is assumed to be know in the poisson distribution). I also talk about how the poisson regression model c...

    At 9:45 i understand that x_4 is determined by everything else and the degree of freedom is three, but i dont understand why we still wouldnt use all four to determine the spread. Why is this. This would suggest that for the case of two numbers we wouldnt divide the sum of the squares by two but by one which seems very unintuitive if we are getting the sd of two values.

    Good content. I have a question : 1.) What will be the structure if labelled dataset to train for hazard ? Can we expect any business setting will have hazard function labelled in the dataset ? that looks quite impossible. How then in that case, it can be used for training(estimating the b0,b1,...) etc. ?
