00:32 When should you use the logistic regression model?
3:20 The model formula
5:06 a real data example on medical school acceptance
10:45 How to fit a logistic regression model using R?
11:35 How to use the fitted model? predictions?
15:35 what is odds?
16:20 How to interpret the coefficients?
17:25 build a logistic regression with multiple predictors

The models in this video are for illustration purposes only. They are not the best models.
The dataset I used in the video: github.com/yz-...
excel file is easier to be downloaded directly. Make sure you click file-import file- import from excel if you are using the MedGPA.xlsx file.
The csv file: github.com/yz-...
you may click copy raw contents, paste it to excel, and save it as MedGPA.csv.
Or you can just load the data from the R package as I did in the video.
The r code with annotations: github.com/yz-...
Feel free to leave me comments with any questions.
