Hi Professor, I have a question about the residual plot, like you said, the prediction is the probability and our response variable is 0 or 1. But why some residuals are greater or smaller than 1 or -1

Is there a video where you discuss null deviance and the other associated output from the summary?

Hi Prof, I was wondering what the format(class1_survival_rate, digits=3) mean? in the survival rate code.

It just sets the number of digits used to display the numerical result.

Thanks, the lecture was very informative. I wanted to know whether the results will have significance in logistic regression if remove out non-significant/not correlated variables applying the linear regression using the 5% significance test.

ok. at 28:50 Sex male is Significant.. what happens to our reference level Sex female? is it significant or neutral?
@ChrisMack

The variable Sexmale is named that way because it takes the value 1 for male and 0 for female. Thus, this variable encodes the gender, both male and female. This variable is significant, which means gender is significant. I could have named the variable "gender", but then you would have to remember whether 1 meant male or female.

Hello sir, Thanks for your great lectures, it was really helpful and useful for me. And I would like to ask could you deliver a lecture on “simulation based on Logistic regression results”?

Can we really use cor() for categorical data? Thank you in advance

Hey @aleksandra you can only perform cor() function on only numeric variables, if your categorical data is A,B,C,D it won't work unless the variable is numeric.
