10:48 ohhhhh, I was just going back and forth between the sections on LDA and QDA in three different textbooks (An Introduction to Statistical Learning, Applied Predictive Analytics, and Elements of Statistical Learning) for well over an hour and that multivariate normal pdf was really throwing me off big time. Mostly because of the capital sigma to the negative 1st power term, I didn't realize it was literally a capital sigma, I kept thinking it was a summation of something!

Thank you for your explanation. I also think at 8:15 the multivariate normal distribution's probability density function should have $\sqrt{|\Sigma|}$ in the denominator (rather than $|\Sigma|$ as you have currently) and it also may be helpful to viewers to let them know that $p$ represents the dimension of the space we are considering

Hi! If the classes are assumed to be normally distributed, does that subsume that the features making up an observations are normally distributed as well?

Yes. If the each class has a multivariate normal distribution than each individual feature variable ihas a single variable normal distribution.

How do you get the values of 0.15 and 0.02? I'm getting different values.
