    One of the best key points to take is the longer form of representation of conditional probability. Never seen this explained in such great and easy detail than here. The longer notation makes everything so easy and simple to understand. You've a great talent to make the subject easily comprehensible for everyone. No other video in UA-cam has put this concept in such a simple way to understand. Thanks & Triple Bam....❤

    This is the best explanation on Bayes' Theorem ever!
    However, It is so difficult for me to use the kind of basic examples that ilustrates the theorem, for the particular task of analyzing differential gene expression between samples. There are available several "bayesian methods" to analyze gene expression changes and I can not understand the relationship of these methods with the theorem's formulation based on conditional probability.
    I am looking forward to see the upcoming videos on the subject. Would you please dedicate some of them to such practical applications of the Bayes' theorem?
    Thanks a lot!

    Thank you for this and all of your many spectacular videos. I was wondering if you could do a StatQuickie or other such video on z-scores if you don't already have one available?
