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...
Logistic Regression Example

This video made me understand variables in 13 mins when my master's course couldn't do it in 2 years. Simply Brilliant!
Hey Martin I love following you. Please do you have course on size calculation
Kindly share the datasets
Thank you so much. You are an amazing teacher!
Great tutorials!! I can't access the data
Thanks a lot, I finally know where that formula of (raw X column)/N comes from. You have saved me from cramming
Hi Mike, been watching since your first video on this course, I was wondering why didn't you get the mean first before calculating squared deviations? Just a question, I love your videos and I'm going to finished these videos btw. Thank you IN ADVANCE
Your videos are excellent. In addition to the high quality content, your clear and focused voice track enhance the learning experience. Many thanks!
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.
Why are the upper and lower fences defined in this way. It seems arbitrary.

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. ?
This video is more disturbing than the fact that I'm taking stats during Summer quarter. Like, how did it keep getting WEIRDER?!?
hello Marin, can you provide us an alternate route to accessing the datasets and scripts. The link to the datasets is not working. Thank you
hi if anyone can share the datasets and scripts would be very much appreciated. I have attempted to contact MarinstatLectures but no response
Finally handy videos extremely helpful for a guy aged 58 wanting to fill the technological gap and for the first time ever seriously considering investin time and energy in R and progressevely make the transition from Excel
Your explanation is so clear! Thank you.
Why we are subtracting 1 from sd and not in mean
Excellent
thank you
Is it just me, or is Dr. Layne Norton's voice echoing through the void yelling about randomized human control trials?
How to deal with cases which do not meet Cox PH Model Assumptions in R? Thanks
Thank you very much
Thanks prof🎉
Thank you,,, from Tanzania ❤❤😊
@marinstatlectures, how is the VAR(X1)=VAR(X2)=...=sigma?
Thank you. I am very much grateful.
Great teacher.
I got it finally once forever. THANKS
Thanks for your work. Great videos
Brainstorming
Magnificent
nice hat 🤣 great teacher
SImply, spectacular! Thk!
Chant Nam myoho renge kyo everyday, to open the inner buddhahood and the path to happiness.
Thank you so much for these videos. You are a lifesaver.
Thank you for helping me. Taking statistics starting this week.
Thank you sir ,you provide all material which i need.
This is wack 👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼 overcomplicating nursery programmes 😢
Dudes writing mirrored in reverse with his left hand. I've practiced things like this along with using "I Am ambidextrous" confirmations to reprogram my subconscious mind and indeed I have become much more mentally creative and left/right handed in function. REALLY HELPS WITH GUITAR. 🎸
You’re such an amazing teacher!!!
The best statistics prof in YT! Thank you so much!!
The best!
Dear Mike, How should i have sequenced classes of this course, i am intresting to have learn
Excellent 👏👏
TY!!!
The fact that no one is talking about your ability to write backwards is pretty "skewed" up in my opinion. Bravo sir.
Literally. What sorcery is this????
Why they used a childs voice in the end! Made me feel like the uploader is unprofessional...
Today is the day I understand the Monty hall problem . Thank you soo much for this detailed video......🙂🙂
Thanks lecturer
I like this ❤😂
